so you gotta pass 1 to the second param there when you're adding the label
#user-interfaces
digital rose
well as i said
when i initially add all of the widgets
to layouts inside of scrollarea
there is like test example
that later on when i trigger an event, changes it's values
and this initial "sample" of basically a rubbish text that is aligned just fine, so i can't possibly imagine why the same set of labels will suddenly change their positions when just changing their text values
i will try what you posted
anyways
well that worked
๐
it's hard to comprehend the logic behind pyqt at times
spoke too early again, i managed to get the first label to be on very top, but it still takes up as much space as it did before
so theres huge space between elements of vbox
i tried setting margin
for everything already and yet to no avail
the thing i noticed is, when content of scrollarea takes a lot of space so that a vertical scrollbar appears
all items are aligned properly
just as in my first initial state of scrollarea with some test text that does indeed take up that much space, that a scrollbar appears
but with less text inside my labels, that basically take up a half of my scrollarea, and that dont trigger the visibility of scrollbar, they are not aligned and have big spaces in between
i tried to set max height for groupbox inside of scrollbar and scrollbar itself, but that didn't do it for me
but that's a big hint

Anyone have any experience working with the PyQt5 built in mouseReleaseEvent ?
sullen thunder
Nevermind, figured out my issue and realized a QTimer was a more efficient method of doing things. (also I did get mouseReleaseEvent working just it didn't work for what I wanted.
karmic shoal
QTimers are good if you want to update at given intervals
sullen thunder
Well, the dilemma I had is I wanted to update a label containing the user net worth when they added a transaction to a ledger. However being they were in different widgets there wasn't a clean signal transfer.
So the timer is a good work around.
I can use the mouse release event to refresh things within a ledger if wanted.
karmic shoal
can't you bind a signal sent when the ledger is updated to a function in your widget containing the label?
sullen thunder
I haven't been able to find a way to send a signal back between the QDialogs. I know that there is a built in Accept(), Reject(), Done() however those close the dialog. Are there other build in signals?
or is there a way to build a signal?
karmic shoal
can you not call the function upon dialog accept?
if dialog_window.exec_() == QtWidgets.QDialog.Accepted:
That closes my QDialog. I don't want to close it during this refresh
karmic shoal
what are you using to take in user input in the QDialog?
sullen thunder
All my data is stored in an Sqlite3 databasw
And the values are submitted via a pusbutton
karmic shoal
oh, then have you tried connecting the pushbutton to the function to update the label?
btw, is this project you're working on open source and/or on github?
sullen thunder
Maybe I am explaining this poorly.
the target label is housed in a QMainWindow widget. The pushbutton, is housed within a QDialog generated within the QMainWindow MdiArea. As a result I have been unable to figure out a signal that doesn't close the QDialog to return to the QMainWindow to update the target label.
no, the project is not open source and/or on git hub at least not currently
maybe sometime in the future. I havent' determined my end use of the program.
karmic shoal
ah, because your project looks eerily similar to something I plan on working on that involves PySide2, a database, currency of some kind and tables
give me a bit I'll try to cook something up
sullen thunder
it's a very common project i think. I am bascially building a personal Mint.com application with my own additions
so, tbh I might attempt to commercialize it in the end. However, I have a lot of development and testing between now and then lol :p
karmic shoal
@sullen thunder are you using PySide2 or PyQt5?

Two problems.
A. The headers for this QTableView are not shown, but my implementation is based off of the official Qt documentation.
https://github.com/spikespaz/jvman/blob/master/special.py#L84-L91
https://doc.qt.io/qt-5/model-view-programming.html#creating-new-models
B. Neither is the data shown.
https://github.com/spikespaz/jvman/blob/master/special.py#L51-L82
This is set up with the following code (data population omitted but I can confirm it's valid).
class AppMainWindow(Ui_MainWindow):
def setupUi(self, window, *args, **kwargs):
super().setupUi(window, *args, **kwargs)
self.availableBinariesTableModel = AvailableBinariesTableModel()
self.availableBinariesTableView.setModel(self.availableBinariesTableModel)
I'd like to tackle the problem with the headers first. What's wrong with my headerData method? Why isn't it shown?
As can be seen here, the correct number of columns are created.
karmic shoal
looks like you don't call the init method of your superclass?

hey, uhm, silly question but I've been trying to wrap my head around having a function that handles getting an entry through a label in Tkinter but I am stuck between either a key event listener or a button. If I bind a key to the function I need the event keyword in the function to make it run, say ' def pressed(event): ...' but if I want a button to handle it too, the command=pressed gives me a wrong amount of arguments exception (command seems to give 0 while event needs 1 event). Is there a way or workaround to handle both through one function or do i have to use two?
small cave
you could use *args as a failsafe since i implied you don't use the event
args will be a blank list from the button but contain the event from the key bind
however if u don't use it it should be fine
nimble lava
that works perfectly for me, thank you. (and yes I wasn't really using the event other than to get the keybind working in the first place)
nimble lava
sorry that I have to ask so quickly but I don't quite get why the code before the sleep does not get 'pushed' onto the screen. Is it just because the sleep activates before the window gets a chance to update?
oh, and e1 is the entry label, sorry for the confusion there
karmic shoal
@lilac raft have you found the solution yet? I can think of one reason that might not work
nimble lava
nvm, fixed it. needed an explicit update.
lilac raft
Nope. Still blank. Is there a methhod I need to call on the view after updating the model? I tried show
@karmic shoal
karmic shoal
do you show() the window after or before updating the model?
lilac raft
AppMainWindow.show() is before, obviously, and self.availableReleasesTableView.show() after updating the data
but it still oesn't explain the column headers
karmic shoal
hm, after you add the data, can you call self.availableReleasesTableModel.layoutChanged.emit()?
lilac raft
ahaaaaahhhh
No cigar yet but look at this

Trying to bind a command to a <<ListboxSelect>> event, using chars.bind("<<ListboxSelect>>", charload). Using this syntax, the method is passed an event argument, and its executed every time an option is clicked. However, i want the function to take two arguments. I can't get it to work, because passing an argument from the function like chars.bind("<<ListboxSelect>>", charload(Thingy)), it thinks its the event method and gives me a not enough arguments error for what i want Thingy to really go to. Also, if i try i put () on the end of charload, the method is no longer executed on the selection of an option, only one when mainloop is started. Any ideas? Thanks

If you want it, here's a recipe for a "keybinding" widget for tkinter.
class KeybindingEntry(tk.Entry):
def __init__(self, master=None, keybinder_inst=None, target_keybind=""):
super().__init__(master)
self.keybinder = keybinder_inst
self.target = target_keybind
self.keys_pressed = []
self.bind("<FocusIn>", self.on_focus_in)
self.bind("<KeyPress>", self.on_key_pressed)
self.bind('<KeyRelease>', self.on_key_released)
def on_focus_in(self, event):
self.keys_pressed = []
self.update()
pass
def on_key_pressed(self, event):
keysym = self.format_keysym(event.keysym)
if keysym not in self.keys_pressed:
self.keys_pressed.append(keysym)
self.update()
pass
def on_key_released(self, event):
v = "<" + "-".join(self.keys_pressed) + ">"
setattr(self.keybinder, self.target, v)
pass
def format_keysym(self, keysym):
keysym = keysym.capitalize()
keysym = keysym.split("_")[0]
return keysym
def update(self):
self.delete(0, tk.END)
self.insert(tk.END, "+".join(self.keys_pressed))```https://i.imgur.com/Tta193J.png all done with just the keypresses, and it clears when you focus it
I find it pretty cool

When appending a row of data to the internal data of a superclass of QAbstractTableModel, should I use self.beginInsertRows() and self.endInsertRows() or are those only for the override of the self.insertRows() method?
For context these are the relevant lines that I'm asking about. The top highlighted method is a override, a direct port of the example in C++. The bottom is my own, as can be seen from the name conventions. Should I use the notifier functions in add_release() as well?

Can anyone explain to me why when I open a file with Pillow and display it, the background changes from white to black?
I somehow go from this
to this
idk why
desert sapphire
The background in the first version isn't white, it's transparent.
how are you showing this?
nimble lava
imported as png, converted to pgm and on a tkinter window. show() has the same result tho
so basically I need to add a while background to the original picture, right?
or is there a way to leave it at transparent?
nimble lava
would a gif work then? Tkinter only supports those two
desert sapphire
tkinter does those two, but with pillow you can do others
nimble lava
well yes but if I want to show it on a tkinter window, I'd have to convert it to one of those formats, no?
nimble lava
o wait, it converts the objects, not the file. I misread that part
doesn't really solve my transparency issue since that happens the moment I import my original png.
at least from what I can tell after trying show() directly after the initial import
desert sapphire
Using a gif could work in that case.
nimble lava
I'll try it out
ok so
gif or not doesn't seem to make the difference but
this gives me a transparent image in the tk window
but if I use show() on the base image then it loses it. Seems to be a show() issue
anyway. Thank you Grote ยฏ_(ใ)_/ยฏ
nimble lava
Ok so, I did some more digging and
I believe I finally found something that works
If anyone is interested:
results in this
relx and rely are not valid arguments for create_image, sadly but it works just like I want it to.

How to you change button color in tkinter
karmic shoal
when you create the Button object you can pass in the bg keyword argument with a valid color -> https://infohost.nmt.edu/tcc/help/pubs/tkinter/web/colors.html
nimble lava
can someone explain why the button listeners are constantly firing?
they just don't stop and idk why
karmic shoal
when you bind a function, you only bind the function name
so that's my_func rather than my_func()
the latter will actually call the function, so your functions run whenever it is bound
nimble lava
so how do I bind a function if I want to give it parameters? Like, I press <a> and give the character 'a' to the function
karmic shoal
there is functools.partial https://docs.python.org/3/library/functools.html?highlight=partial#functools.partial
nimble lava
if I understand that right, I'd have to make a new partial for each of those. Is that correct?

a_press = partial(player_guess, character='a', canvas=hangman_canvas
wait that didn't come out right
karmic shoal
yes, that's the gist of it

Is there a way to disable/remove the text label in these radio buttons entirely?
@manic lodge https://www.pygame.org/docs/ref/transform.html#pygame.transform.scale looks like this might be what you're looking for
manic lodge
Yeah , ive been doing it for a few hours in help 4 and going through alot of code with it but thank you โค๏ธ
sudden coral
@proper glade Which text labels? The things that say "Sampler"? They look like buttons to me.
proper glade
@sudden coral the little empty space to the right of the radio.. thing. im assuming it's the place where the text is supposed to go.
but since it's empty, it's just taking up space and offsetting the button itself
this is what it looks like without the radiobutton so im fairly sure it's not a matter of outer spacing
sudden coral
I see. Didn't know they had labels attached to them
I'm not seeing any obvious way to remove it from the docs
proper glade
same
i'm thinking there might be some way to do it via stylesheet
but it doesn't seem like there are any good docs for those per widget either
sudden coral
That's an interesting approach, though I'm not sure how the label would be selected
it doesn't seem to expose the label publicly anywhere
proper glade
oh yeah source code ๐
sudden coral
Ok so some progress
Unexpectedly, qabstractbutton actually provides the functionality for displaying text
So let's look there, as the radio button would inherit from qabstractbutton
proper glade
on it
ok, tracked down the radiobutton drawing logic to here: https://code.woboq.org/qt5/qtbase/src/widgets/styles/qcommonstyle.cpp.html#1367
looks like it is directly painted unfortunately
oh no wait, got confused
there is a separation between the button and the label, yes
in stylesheet form this might be QRadioButtonLabel or QRadioButton.Label. so I'll try those
sudden coral
I don't see any mention of it in https://doc.qt.io/qt-5/stylesheet-reference.html
It's not a sub control
proper glade
i'm guessing based on the cases there in the source
there's both CE_RadioButton and CE_RadioButtonLabel
though I can't find where the drawing for CE_RadioButtonLabel actually gets invoked
oh man that stylesheet reference is gonna come in so handy. didn't know about that, thank you
sudden coral
It's here by the way https://code.woboq.org/qt5/qtbase/src/widgets/widgets/qradiobutton.cpp.html#248
proper glade
that's only for CE_RadioButton though, no?
sudden coral
Yeah
Look back in qcommonstyle.cpp
when the radio button is drawn
it then calls draw again for the label
but basically what you need to do is override the paintevent
proper glade
ohhhh that's what proxy()->drawItemText is doing
i see i see
wait no, i went to the wrong point
sudden coral
line 1378
sudden coral
I'm not sure the best way to approach this
Maybe use a custom QStylePainter?
I never really messed with this "lower level" stuff too much
proper glade
i'm gonna try and find out how much control i can get over proxy() and maybe override its drawControl, though that does sound like a pita.
QStylePainter huh? i'll look into it
thanks so much btw
sudden coral
Yeah, that's what drawcontrol is called on
At a glance, that may be the way to go
Some more useful stuff
proper glade
TIL
sudden coral
Doesn't seem that bad actually
proper glade
yeah, here's hoping ๐
sudden coral
It is ridiculous that disabling it is not just a standard feature
Which makes me wonder if we're missing something obvious
Like something in the stylesheet
By the way, your UI takes inspiration from FL, right? @proper glade
Looks a lot like the channel rack
proper glade
@sudden coral yep, im basically reimplementing it inside Reaper
and I agree it's quite ridiculous that stuff this simple seems so complicated
proper glade
so i added this transparent overlay widget for drawing a curve over the bars and it works well for the most part. unfortunately, when you minimize and restore the window again it just freezes. its paintEvent is never called again. i have no clue why
ok, i think i might have discovered a bug?
it seems that when you restore minimized windows they don't call changeEvent and therefore the restoration isnt propagated correctly to their children
proper glade
ok, i fixed it by making a custom QLayout for overlapping widgets
class OverlappingLayout(Qt.QLayout):
def __init__(self):
super().__init__()
self.items: List[Qt.QLayoutItem] = []
def addItem(self, item: Qt.QLayoutItem):
self.items.append(item)
def itemAt(self, index):
try:
return self.items[index]
except IndexError:
return None
def takeAt(self, index):
self.items.pop(index)
def sizeHint(self):
return Qt.QSize(1,1)
def setGeometry(self, rect: Qt.QRect):
super().setGeometry(rect)
for item in self.items:
item.setGeometry(rect)
def count(self):
return len(self.items)
definitely needs some work (looking at you sizeHint) but it's getting the job done for now
proper glade
ok, that was completely useless. QStackedLayout already lets you overlay widgets.

would i need to do something like self.newcoordx and self.newcoordy
tight bear
Been a while since I've done pygame collision checks, but there oughta be something.
tight bear
Ok, you do want to use collidepoint, but there's something with the placement.
Because the rect doesn't know about the self.x and self.y
manic lodge
sprites_clicked = [sprite for sprite in all_my_sprites_list if sprite.rect.collidepoint(x, y)]
could this be useful?
tight bear
Nah.
If you change back to using piece.frame.get_rect().collisionpoint(x,y), it triggers correctly when you press the top left piece.
As in, it triggers all pieces, because that's where they are technically placed.
manic lodge
collidepoint?
tight bear
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
x, y = event.pos
for item in objects:
# Deselect all pieces
item.selected = False
# Select targeted piece
if item.frame.get_rect().move(item.x, item.y).collidepoint(x, y):
item.selected = True
.move?
tight bear
This seems to work.
So, the problem with the collision detection is that the rect/image is technically placed at (0,0)
Blit doesn't move an image, it just draws it at a location.
So all images are piled up at 0,0 which doesn't work for the intended collision check. I'm sure you could move the image some other way earlier, or blit does something odd.
tight bear
In either case, you could move the collision check into the class itself, like a click where it does that code called for each piece atm.
You'll notice that the select boxes overlap weirdly, and that's because they're currently outside of the image due to widthxheight and thickness 3
manic lodge
yeah i gathered that, would a fix be to have a border?
Or just to reduce thickness
thickness 2 seems to work fine
tight bear
Pygame's shape draw functions are kind of awful, so you'll just have to try it out.
Like it's unclear whether the lines points are in the middle of the thickness or on the top left corner
And it's different for the right and bottom
manic lodge
yeah its weird in that way
i saw that earlier
tried to select bottom right
and it was off the screen

its like a fade

for item in objects:
if item.selected == True and item.selected not in selected:
selected.append(item)
if len(selected)==2:
selected[0].swap(screen, selected[1])
print(selected)
for item in objects:
item.selected = False
item.draw(screen)
I would suggest keeping the piece.selected as your only data. When clicking on a piece, check if it is not selected and loop through all other pieces.
If another piece is selected, do a swap of their x/y

i have a problem with the layout. i have two tabs in my GUI. In the frist one i have a QHBoxLayout and QVBoxLayout. Here is the source Code: ``` h = QHBoxLayout()
h.addWidget(self.fjsr)
h.addWidget(self.zeile)
h.addWidget(self.uploadbtn)
v = QVBoxLayout()
v.setAlignment(Qt.AlignTop)
v.addLayout(h)
self.tab1.setLayout(v) ``` I send u a picture how the layout looks like:
Then i have the second tab where the buttons are created withe the loop: ``` box = QVBoxLayout(self)
self.tab2.setLayout(box)
scroll = QScrollArea(self)
box.addWidget(scroll)
scroll.setWidgetResizable(True)
scrollContent = QWidget(scroll)
scrollLayout = QVBoxLayout(scrollContent)
scrollLayout.setAlignment(Qt.AlignTop)
scrollContent.setLayout(scrollLayout)
scroll.setWidget(scrollContent) ``` there i create the buttons in a loop and can scroll. i send u a picture:
how can i change the layout in the second, that it looks like the first tab?

@Jan you could use nested layouts, multiple horizontal inside a vertical. Or grid layout.
tight bear
@manic lodge Working on a project atm, but can help out later!
You deselect all items by looping over them and setting select to False.
manic lodge
for item in objects:
item.selected = False
I did that here but it didnt seem to work
and no worries! gl on ur project โค
if item.frame.get_rect().move(item.x, item.y).collidepoint(x, y):
item.selected = True
break
this sets it back to true when i get back round
I dont get how though because:
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
wouldnt be true
tight bear
@manic lodge Solved it?
tight bear
Pastebin it!
manic lodge
Ok, theres one problem rn
Ive added pokemon and dog images at random too it
So youll have to download 800 pokemon imgs
or just change it to a name
tight bear
What was wrong with mouse button down?
tight bear
Sure, but you could still use pygame.MOUSEBUTTONDOWN and event.button
manic lodge
I mean i did try still using them it just didnt work
Might of been something i was doing
tight bear
When it comes to swap, there's an elegant solution to swapping two variables
manic lodge
store = [item2.x,item2.y,item2.frame]
item2.x, item2.y,item2.selected = self.x, self.y, False
self.x, self.y, self.selected = store[0], store[1], False
I tried this
tight bear
def swap(self, other):
self.x, other.x = other.x, self.x
self.y, other.y = other.y, self.y
self.selected = False
other.selected = False
we need screen? or draw?
tight bear
Well, the pieces are drawn every frame, so changing their position will update the place they're drawn immediately after the events.
The only place you'd ever need blit is in draw. Elsewhere you could update x,y however you want.
manic lodge
ohhh! that makes a lot of sense... because were drawing it on swap then draw
when we should just do draw
tight bear
Give me a moment, got some food in the oven
manic lodge
Alright no worrie
tight bear
Ok, I think the logic might've been a bit warped, trying to swap pieces in the update as long as there are some in a buffer.
Any kind of swapping should occur right as you get a mouse click event.
How it could be structured is this:
- Try to find a selected piece (loop over all and store in a variable if found)
- Do mouse collision check with all pieces to see if one is found
3.1) If selected piece exists, swap current piece and selected piece
3.2) If no selected piece exists, set selected
manic lodge
oh and that should be in the event?
tight bear
def gameLoop(width, height, random_indicies, screen, frames, split,objects):
clock = pygame.time.Clock()
while True:
# Check events
for event in pygame.event.get():
# Quit event
if event.type == pygame.QUIT:
pygame.quit()
exit()
# Mouse click event
if event.type == pygame.MOUSEBUTTONDOWN:
mx, my = event.pos
if event.button == 1: # Left
# Try to find selected
selectPiece = None
for item in objects:
if item.selected:
selectPiece = item
# Look for click collision
for item in objects:
if item.collision(mx, my):
if selectPiece:
# Another piece is selected: swap
selectPiece.swap(item)
selectPiece.selected = False
else:
# No other pieces are selected: select
item.selected = True
if event.button == 3: # Right
# Deselect all pieces
for item in objects:
item.selected = False
# Draw items
for item in objects:
item.draw(screen)
pygame.display.update()
msElapsed = clock.tick(60)
Yeah, or to make it look much nicer, I'd suggest moving it into a function.
Such as clickSelect or deselect perhaps.
Also, in this example, I changed the swap function like shown before, and moved the weird collision rect thing to Piece.
def swap(self, other):
self.x, other.x = other.x, self.x
self.y, other.y = other.y, self.y
def collision(self, x, y):
rect = self.frame.get_rect()
rect = rect.move(self.x, self.y)
return rect.collidepoint(x, y)
The only thing swap should do is swap their positions (or images). Collision checks with the mouse x,y and returns True if it is targeted.
When a swap occurs, you know that the only selected piece has to be selectedPiece, which we can safely deselect.
manic lodge
this makes a lot more sense structurely
Gotcha, so we never have 2 selected pieces
Its always just 1 , with another one being found
tight bear
# Try to find selected
selectPiece = None
for item in objects:
if item.selected:
selectPiece = item
# Look for click collision
for item in objects:
if item.collision(mx, my):
if selectPiece:
# Another piece is selected: swap
selectPiece.swap(item)
selectPiece.selected = False
else:
# No other pieces are selected: select
item.selected = True
It's all about this code here, when the mouse is clicked.
manic lodge
selectPiece = None
for item in objects:
if item.selected:
selectPiece = item
this finds THE one selected
Ok, understood
tight bear
Yep yep! What happens when no piece is selected?
tight bear
In those four lines you posted. What happens to selectPiece?
manic lodge
If another piece is
it gets assigned the item where its selected
aka the only one which is selected
tight bear
And if there are no selected?
manic lodge
Nothing, it carries on until something is selected
tight bear
Yeah, and then selectPiece will remain None
This is why you can call if selectPiece: later to see whether there is one or not.
Anyway, you get the hang of it
Next up, you need some kind of check for when all pieces are in place!
Something that oughta be called after a swap, such as checkIfDone
manic lodge
Should we make it so it turns green if its in the right position
So that we can check for each piece
manic lodge
yeah definetly! its coming together nicely!
if the image is done
the collision will be in that spot?
tight bear
What do you mean?
tight bear
I think what would be best is to give each Piece its "correct" position when it is created. You have that knowledge when you create them.
for index, frame in enumerate(frames):
num = random_indicies[index]
x = width * (num % split[0])
y = height * (num // split[0])
yeah the x,y is the correct coords if im not mistaken?
tight bear
You have index, which is the correct ordered index of the frame, and num, which is chaotic random.
Yeah, you could calculate the correct x,y in just the same way, using index instead of num
Could calculate both, pass it into Piece constructor and save x,y as coordinates and goal_x, goal_y as the goal to compare with later.
manic lodge
piece = Piece(frame, x, y)
so when u have this
we need to save it as self.goal_x and self.goal_y?
tight bear
piece = Piece(frame, x, y, goal_x, goal_y)
Then you need to add these to __init__ and save them into self the same way.
manic lodge
goal_y = height * (index // split[0])
Lastly, you could make a function in Piece such as isCorrect or something that compares these coordinates and can be called in draw or upon swap.
Yeah, that looks alright, same way as the y coordinate.
manic lodge
yea but with index not num ๐
tight bear
To explain how the weird index % split[0] and index // split[0] works, we can look at what index, x, y are.
index: 0 x: 0 y: 0
index: 1 x: 1 y: 0
index: 2 x: 2 y: 0
index: 3 x: 3 y: 0
index: 4 x: 4 y: 0
index: 5 x: 0 y: 1
index: 6 x: 1 y: 1
index: 7 x: 2 y: 1
index: 8 x: 3 y: 1
index: 9 x: 4 y: 1
index: 10 x: 0 y: 2
index: 11 x: 1 y: 2
index: 12 x: 2 y: 2
index: 13 x: 3 y: 2
index: 14 x: 4 y: 2
looks somewhat like how u do binary splits?
tight bear
X will cycle from 0 to (width-1) and Y will become each line, ticking up as index goes past width.
More or less.
It's just rather useful math to know.
manic lodge
Yeah so each x, y has an index
So for each line
it has width amounts
and for each width amounts it has a y value attached
def isComplete():
if self.x,self.y == self.goal_x,self.y:
self.isCorrect = True
elif other.x,other.y == other.goal_x,other.self_y:
other.isCorrect = True
What is other?
tight bear
Well, the icComplete should only really return True or False whether that one piece is correct or not.
Pieces shouldn't try to keep track of each other.
Plus, there's no other parameter in the function, so it'll result in an error.
Plus, you're comparing y with y.
manic lodge
yeah i gathered that, also i made the same mistake as before
tight bear
And self_y doesn't exist.
manic lodge
im putting it in swap but it draws every turn
tight bear
Well, first off, what would you like to use correct check for?
tight bear
No, I mean, what could you use the isCorrect check for?
manic lodge
if its in the right position?
tight bear
Was thinking more about where you could try using it right now.
Say, in draw for instance. If it's correct, draw a green border.
manic lodge
elif self.isCorrect == True:
width, height = self.frame.get_size()
pygame.draw.rect(screen, (0,255,0,50), (self.x,self.y,width,height), 2)
Ah, i did this just on insentive xD
tight bear
Yeah, tis nice!
tight bear
Two ways to do this. Now you're setting self.isCorrect to be a value, so you will need to set it in init and update it upon swap.
An alternative is that you have a function like self.isCorrect() that returns True or False, just doing a check.
tight bear
Sounds good.
manic lodge
So we have to take through both self and other so we can see both
and then if
def isComplete():
if self.x,self.y == self.goal_x,self.y:
self.isCorrect = True
elif other.x,other.y == other.goal_x,other.self_y:
other.isCorrect = True
but self_goal
tight bear
I would not recommend sending other into that check.
Each piece should be able to determine its own state.
tight bear
def isCorrect(self):
return (self.x == self.goal_x) and (self.y == self.goal_y)
Here's the simplest version.
manic lodge
ah, forgot u can put "and" in returns
tight bear
Alternative is spreading it out to make it more readable.
manic lodge
I understand that, so i think itll be fine
tight bear
Anyway, then all you need in draw is if self.isCorrect():
tight bear
Well, you can't really name both the function and variable the same thing.
tight bear
Note that whenever you check if a boolean == True, it is the same as writing just if boolean:
For boolean == False, you can use if not boolean:
manic lodge
elif self.isComplete(): for example?
tight bear
Anyway, you might notice that it won't draw any green borders. Something else is drawn first.
Sure.
manic lodge
and if self.selected?
if not self.selected
if not self.selected and not self.isComplete():
Just change the order.
If it is correct, then it is not selected.
So not selected will always draw first.
Try flipping it around. If no other special cases exist, draw it black. First check if selected, red, or complete, green.
manic lodge
def draw(self, screen):
screen.blit(self.frame, (self.x, self.y))
if self.isComplete():
width, height = self.frame.get_size()
elif self.selected:
width, height = self.frame.get_size()
pygame.draw.rect(screen, (255,0,0,50), (self.x,self.y,width,height), 2)
else:
width, height = self.frame.get_size()
pygame.draw.rect(screen, (0,0,0,50), (self.x,self.y,width,height), 2)
like so?
tight bear
Mhmm!
If you want to keep it similar to the self.selected, you could indeed do something like self.correct and set it correctly whenever you do a swap.
However, in puzzle games it might not be super fun if you know immediately when a piece is correct.
But rather only when all pieces are correct and you're done.
manic lodge
exactly! so if i create one with
for item in object:
if item.isComplete()
x+=1
if x == len(objects):
turn all green
tight bear
Yep, that works.
manic lodge
so in startup
itll be screen?
screen = pygame.display.set_mode((size[0], size[1]))
screen.fill((255,255,255))
then it turns white
but things still duplicate
tight bear
That works as well. That fills the background.
However, for each piece, you need to fill the surface before blitting the image.
manic lodge
oops xD
frame.fill((255,255,255))
good white full game xD
im confused
it just
whites the whole
tight bear
Hrm, could be that you're filling in the image, which overwrites it.
For now you could fill the screen though.
tight bear
Might also want to fill it before drawing all objects. Might notice that if you start moving pieces outside of their positions, the background will look trippy without fill.
manic lodge
that bad
tight bear
Definitely not. That is not Piece's responsibility.
Plus only one piece would show, most likely.
manic lodge
yep
as itll fill the est
rest*
while True:
screen.fill((255,255,255))
right, well i have to rest so ill speak tomorrow! thanks again ur a life saver!

note that you can only use 1 layout in a master window
dawn schooner
hello, how to kill Pyqt5 window?
dawn schooner
self.window = QtWidgets.QMainWindow()
karmic shoal
self.window.close() closes that window
karmic shoal
it's self.window.close(), just noticed I made a typo
if you did that an it still won't close, can you post your code?
dawn schooner
yea i got error when it was windows so i tried window
still samae
Here it is bro, plz check and help me
line 105 andd line 120
lemme change windows in line 120
that window wont go ๐ฆ
tried many thing
karmic shoal
actually, I'm not sure why you have if __name__ == '__main__': inside the class
!e
class Test:
def __init__(self):
print("init")
if __name__ == "__main__":
print("main")
test = Test()
@karmic shoal Your eval job has completed.
001 | main
002 | init
can you try having whatever is in main in a class method, then run that method in __init__?
dawn schooner
i want to run two function at the same time
the gui and the voice
it say's lisa is not defined
karmic shoal
that's because you have it as def lisa(): in your class
if you put a @staticmethod decorator on top of def lisa():, you should be able to call it as self.lisa
dawn schooner
but it wait for audio to finish than it brings up the Gui
Plz Kosa any way i can run both Gui and Voice of lisa?
karmic shoal
can you show me the code now?
dawn schooner
with your edits of staticmethod?
karmic shoal
the whole thing
dawn schooner
i have three different code
this one is just taking input and inserting into data
karmic shoal
you had lisa running with multiprocessing, but then you removed it, can you try adding that back in?
dawn schooner
Yea this one plays Audio as well as display Gui
i think when i run os.system(python3 first.py) it wont move onto next command until thata script is finished
because keyboardintterupt is working now
because of self.window.close
ok now atleast i know self.window.close works
Now i understand why it won't work at the same time
Thank you @karmic shoal โค
i've found an alternative by using a gif splashscreen for 5 sec while it plays audio and later on into the gui
i'll use static method dnw

is there some Qt user somewhere ?
I have a bit of a pickle
So, i'm making this ruler
I used a QSplitter with some customization over the handle
but err...
due to the handle size, I can't really move them on the extrem top or bottom
any idea ?
rn, I'm trying negative margin/padding, that's how deseperate I am
proper glade
@mighty frigate you could scale down the rainbow rectangle so the top and bottom edges line up with the handle
and fill the top/bottom with transparent rectangles
then there's an attribute you have to turn on, WA_TranslucentBrackground or something like that
is the rainbow a QFrame?

i want a pyqt window like Cortana ๐
proper glade
@dawn schooner https://code.google.com/archive/p/qterminalwidget/ found this. it's in c++ qt though so youd have to be up for porting it over to pyqt
you could take a look at the source for some ideas at the least
proper glade
https://github.com/lxqt/qtermwidget here's a project based off of that one
ah i see. hmm i havent been able to find any ones alrady made for pyqt
oh wait, they have a pyqt binding there

maybe i can make a window
proper glade
https://github.com/lxqt/qtermwidget/tree/master/pyqt not sure how it works though, let me dig a bit more
dawn schooner
take my input into a textbox
and display output in textbox
i just realize
that would be simpler
right?
proper glade
yep, that's always an option
dawn schooner
since i don't want to type any commands , just a program like cortana
to take microphone input
proper glade
though youd have to handle things like ctrl+c for termination and the like if you want that
ah i see
dawn schooner
i just realize that ohh that was simpler than i thought itd be
just making it complicated xD
onyx sky
i'm trying to connect my exit handler using pyside2 but all i'm seeing is overloading a new closeEvent method on your class, but i'm not having it as part of a class. Is there a way to do that?
mighty frigate
@proper glade y it is (QSplitter)
proper glade
ohh i see, so the rainbow is drawn on the QSplitter itself
mighty frigate
y as stylesheet
proper glade
y?
mighty frigate
yes
proper glade
oh
hmm well the only thing i can recommend then is to maybe
use a QGraphicsView and add the splitter, use stylesheet to remove its border and background + a rectangle with the rainbow inside it
mighty frigate
oh good idea
proper glade
and make sure the rectangle is below the splitter of course
mighty frigate
I can't do that tho :/
the ruler will already be in a QGraphicsView
in my experience, a QGraphicsView inside another one is recipie for disaster
proper glade
how so
and in any case, you could add the rectangle and splitter separately to the original QGraphicsView then
mighty frigate
from what I remember (it was some years ago) it can induce problems like fonts breaking, no transparency (black), etc
rn I left that issue sitting
i'm working on the graduation
nimble lava
can someone help me figure out why the lines and boxes don't line up :/
image is scaled down to 600 x 450 from 2048x1536
so boxes should be 50px wide
but this doesn't allign
box_size is 600/12, so 50
desert sapphire
I see 2 sets of lines
nimble lava
yes the ones that don't line up with the circles are from the image used as background
desert sapphire
Are those light lines from the background image?
nimble lava
yes
desert sapphire
My best guess is that it's a scaling issue.
Or the orginal squares on the image aren't the exact size
nimble lava
my only explanation is that 2048/600 and 1536/450 aren't exact integers and might cause havoc. Everything else lines up nicely with the resolution i chose.
desert sapphire
Do the lines overlap if you do the 2480x600 version instead of the scaled one?
nimble lava
original is 2048x1536 and I can't display fit the whole thing but doesn't seem to be the case
desert sapphire
You don't need to see all to see if they line up
nimble lava
not looking good skipper
desert sapphire
Looks like the light lines are just a bit bigger
Going to the bottom left they stick out a little bit more each box
bottom right*
nimble lava
it's 2 pixels off per side of a box apparently
lines up now
but
I can't scale a 2 pixel issue down
best I can do is use half the original size and add 1 to the box size from the looks of it
:/
agile moss
Is that the ancient game?
nimble lava
y
agile moss
Nice. I should probably shut up, because this is off-topic and I don't have anything useful to say. Would love to see this in #303934982764625920 later though
nimble lava
if i make it work eventually lol
half latch
So your boxes are 52 wide now ?
nimble lava
no, since the original is off 2 per box
I can at best use half the size and adjust by 1
so I got roughly 86 pixels per side
roughly cause I'm dropping 1/3 a pixel per box to make it an integer
but it's as close as I can get
half latch
Can you send me the background image ? Want to try if I can do anything better
nimble lava
sure
tight bear
Seems as if lines and images are overlapping, which could make it tricky to line up nicely.
But if tiles were placed with a small pixel gap between each other where the line could be drawn, that's as perfect as you can get.
desert sapphire
Where is it from?
tight bear
Are you drawing 2 lines now?
nimble lava
no, the lines I am drawing on top is for me to know where to place the pieces
basically
I am making the game for a forum so a guy gave me the image to work with
tight bear
It looks really good though, so the gap doesn't really matter.
But imagine placing a bunch of 50x50 images next to each other. Each image would occupy 0-49, 50-99, etc
Meaning wherever you'd draw a single line, it'd be overlapping one edge, which is slightly off center still
In which case you could align tiles with a (box_size + 1) gap so that lines are never overlapping tiles. 0-49, 50, 51-100, 101, 102...
desert sapphire
Is the right side on the original image even a full square?
nimble lava
can't tell you for sure tbh. I can only assume they are supposed to be. but since the width/12 + 2 align with the background lines on the original
I can only say no
is there a point in leaving a gap if there is none in the original tho?
tight bear
As long as it looks good with the lines.
When it comes to making sure your tiles are squares, just check the size of the image? I assume they're scaled down in game?
desert sapphire
The problem seems to be that you are dividing it in perfect squares while the last element is a rectangle
also the bottom row
nimble lava
the ratio works for the amount of squares
its 12 wide and 9 high, 2048/12*9 is my height of 1536
issue is probably what Grote meant.
tight bear
Well, 172*12 = 2064, not 2048
half latch
The last one of each row is 156*172
nimble lava
how did you figure that out btw
tight bear
In your code, what have you set box_size to?
nimble lava
basically width/12 + 2 for the 2048 one
or +1 for the 1024
so I was assuming squares, yes
tight bear
How about we do this the other way around.
half latch
Now you have the dimensions, it should be easier ^^
tight bear
Set a fixed box_size, since your tiles should be fixed size, then you calculate the window size from that.
2048 isn't divisable by 12.
nimble lava
y my approx is 170 cause i convert to int then +2 to match
How do I map my pic onto the calculated window size tho. If I just stretch to fit it won't line up right just the same
tight bear
Could you send one of the tile images?
nimble lava
it's one big one. I suppose I'd have to crop out one tile and make my own
actually, that's prolly what I should be doing
tight bear
That would easier to manage, and saves processing time as well.
Make sure each tile image is a specific square size you've given it, which you can then use to calculate distances in the game.
nimble lava
but loading one big image into the background should be faster than 6 smaller ones to make the big one, no?
tight bear
That's true. You could still keep your images in one spritesheet, just as long as the size is correct.
I assume you're using subsurface or whatnot to extract each tile.

in all honesty, I was just gonna crop out one of the paper tiles in gimp and paste them onto the bottom and right edge
so I'd have an image that works
I'm not building the image tile for tile but I was just using the whole thing as one background image and refreshing each tick. Probably a bit cruder than you imagined ^^,
tight bear
Oooh, it's really just one large image at the moment?
tight bear
Oh, and the original image already has lines drawn on top.
nimble lava
yes
tight bear
Aight sorry, figured you were playing around with the actual tiles.
nimble lava
I wish. Then the different size wouldn't have happened
tight bear
But then it might just be the original image that isn't perfectly square at the end.
nimble lava
which is why I am in gimp right now. To finally fix that issue ^^

Hey i'm trying to figure out how to place labels when a button is pressed. The issue is that the placed labels are on top of each other and they have no variables linked to it
i tried using a variable x but it doesn't work at all
(forgot to mention i'm using tkinter)
nimble lava
are you using pack/place/grid?
sinful oasis
grid
nimble lava
are you keeping track of button presses to vary column and/or row of each label?
sinful oasis
nope
nimble lava
well then you are just pasting them over each other. Grid widgets need separate placements. So you want a variable that increases with each press or call of your create label function and use that to vary your placement of the label
so you use a global variable inside the function that makes your labels
define like x = 0 in your main or just below your imports and put global x right below your function def, if you use x in the declaration after that, you are referencing the one outside the call. So if you add 1 that means that addition gets saved even after the function ends.
sinful oasis
what i'd like to do is when button is pressed create a label in row=3 bound to a variable, if pressed again label in row=4,again bound, row=5 etc..
nimble lava
can you paste or snap your button code here?
sinful oasis
boutonvalidation = Button(mainframe, text="Ajouter",command=lambda: self.spellencooldown(tkvar.get(), tkvar2.get()))
def spellencooldown(self,perso, spell):
Label(mainframe, text=spell).grid(row=x, column=1)
you are referencing an x that has no value
nimble lava
what you want is something like
def spellencooldown(self, perso, spell):
global x
Label(mainframe, text=spell).grid(row=x, column=1)
x += 1
what i did before is define x=3 (row=1,2 are used) then x+= 1 after label is created
here is my code
i defined x=3 defore the class
sinful oasis
i do self.x = 3 then use it ?
nimble lava
then you end up redefining it as 3 every call
sinful oasis
how do i get around it ?
Ok got it working now how do i create a new variable each time ?
For the label
d["labelspell{0}".format(x)]
i saw this as a solution
but i'm not sure
desert sapphire
What variable needs to be created every time?
sinful oasis
a variable linked to the label that gets created
nimble lava
I thought you only wanted to put the labels next to each other
desert sapphire
Is it bound to the command?
sinful oasis
the label creation ?
desert sapphire
The var for the label, is that the label itself, or a value for the command of the label?
sinful oasis
label * l itself so that i can edit it
desert sapphire
I can think of something.
What kind of data will be in this variable and how would it change?
sinful oasis
The label itself is just for display purpose but his coordinates will be used to delete the line. The line would be composed of Nameofspell,cooldown. I am gonna make a button that will tick down the cooldown(so i have to edit this label) and if the cooldown=0 then delete the line
desert sapphire
When you use a Stringvar you can edit that and the text on the label will change.
desert sapphire
variable = StringVar()
Label(root, textvariable=variable)
variable.set("This is the text of the Label")```One stringvar per label you want to change
sinful oasis
But i won't have a finite number of labels
desert sapphire
How are you keeping track of your labels?
sinful oasis
I'm going to make a picture to explain
The user chooses a character and a spell then adds it to the cooldown"list"
just missing the cooldown label that will be next to "Spellname that will be in cooldown" the button to tick down the cooldown
desert sapphire
They'll have to be saved at some place in the code, a dictionary peprhaps
sinful oasis
llike this d["labelspell{0}".format(x)]
desert sapphire
Something like that yes. Depends a bit on what things need to be saved.
So it needs to be at least the name of the cooldown label
desert sapphire
There should also be a cooldown time saved or not?
desert sapphire
Don't worry.
I'm cooking diner right now.
I quickly put this togheter as an example of a countdown.
from tkinter import StringVar, Tk, Frame, Label, Button
root = Tk()
spells = {}
spells["Leviosa!"] = {
"title": StringVar(),
"default_cooldown": 2000,
"cd_duration": StringVar(),
"cooldown": 0
}
spells["Leviosa!"]["label"] = Button(
root, textvariable=spells["Leviosa!"]["title"], command=lambda: activate(spells["Leviosa!"]))
spells["Leviosa!"]["title"].set("Leviosa!")
spells["Leviosa!"]["label"].pack()
Label(root, textvariable=spells["Leviosa!"]["cd_duration"]).pack()
def activate(spell):
spell["cooldown"] = spell["default_cooldown"]
spell["cd_duration"].set(spell["cooldown"])
root.after(100, countdown, spell, 100)
def countdown(spell, reduction):
spell["cooldown"] -= reduction
spell["cd_duration"].set(spell["cooldown"])
if spell["cooldown"] > 0:
root.after(100, countdown, spell, 100)
root.mainloop()
im trying to draw a tiny triangle in a 16x16 pixmap with QPainter
this is what it looks like zoomed in
just... why
both of those lines have the same length and in theory should look exactly the same but flipped horizontally
but for some reason qpainter doesn't draw lines consistently
desert sapphire
16 has no middle
proper glade
ive tried using a qpainterpath too, and a polygon
@desert sapphire left one draws from bottom left to 7, 0, right one draws from bottom right to 8, 0
sinful oasis
will try this but pretty sure it's gonna work thanbks !
sudden coral
@proper glade Did you ever solve that? I'm just curious as to what the solution was.
proper glade
@sudden coral i ended up using good old bresenham to plot the points manually
looks like qt's line drawing algorithm isn't too great
sudden coral
Bah, lame
proper glade
unfortunately this means missing out on antialiasing, since painter.drawPoint doesn't take care of that
sudden coral
That's just another thing for you to re-implement yourself ๐
proper glade
sudden coral
I was under the impression you didn't want AA anyways
proper glade
i had it on at first and the triangle looked wonky
so i turned it off to see what the deal is
and lo and behold it's wonky all the way down
sudden coral
That skimage function looks promising
proper glade
here's hoping ๐
proper glade
nope, the skimage functions are weird too
proper glade
alright, finally got something i'm ok with
proper glade
@mighty frigate
pixmap = qt.QPixmap(14, 15)
pixmap.fill(qt.Qt.transparent)
painter = qt.QPainter()
painter.begin(pixmap)
painter.setPen(qt.QColor(255, 255, 255, 255 * .1))
for x, y in zip(*line(0, 14, 7, 0)):
for iy in range(y):
painter.drawPoint(x, iy)
painter.drawPoint(14-x-1, iy)
for x, y, alpha in zip(*line_aa(0, 14, 7, 0)):
painter.setPen(qt.QColor(255, 255, 255, 255*alpha*.1))
painter.drawPoint(x, y)
painter.drawPoint(14-(x+1), y)
painter.end()
up_arrow_pixmap = pixmap
down_arrow_pixmap = pixmap.transformed(qt.QTransform().scale(1, -1))
i ended up combining the two of them
mighty frigate
noiceยฒ
proper glade
and instead of drawing both lines i drew one and reflected the points on the other side
mighty frigate
dem your drawn it yourself ??
proper glade
more-or-less ๐
scikit deserves a lot of credit though
i have no idea how to implement antialiasing
proper glade
oh, nah, all of those are pushbuttons
mighty frigate
aaaaaah
proper glade
their pixmaps are cached too
proper glade
lol no need to reinvent the wheel there ๐
proper glade
here's a better look at the overall thing
it's a step sequencer primarily intended for programming drums
mighty frigate
that's neat
proper glade
it's heavily based off of the one in FL Studio
mighty frigate
all in python ?
proper glade
yep
proper glade
gotta be cause I want to integrate it with another DAW that has python scripting capabilities
the performance is alright so far
mighty frigate
okay

hey ๐ i am using tkinter and i want to have a button on the bottom of my frame, the issue is that i am using grid and i cannot enter row or column because i have labels that my code add each button press
i figured ou t a way around but i want to make sure there is no other way (my "fix" is to remove the button each time a new label appears and place the button one row lower etc..)
serene spoke
Just updated Codingg! Built with nothing but Python and Tkinter
azure bolt
Im trying to present data exactly like in the picture, but in a tkinter window. Whats the best way of doing so?
azure bolt
Its pretty much stock data, thats all packed into an array. Curious if anyone has any suggestions
serene spoke
Oh my. I wasn't aware that Tkinter couldn't load a font from a file. Hmmmm
trim rapids
Can someone tell me how they would go about stacking a frame on top of a frame in tkinter?
@ me if you know
serene spoke
@trim rapids as I understand it, you can't
trim rapids
damn alright thanks @serene spoke
trim rapids
Is there a way to remove all widgets in one command
Instead of .grid_remove each widget
@ me if you have an answer
serene spoke
@trim rapids no

Hey everyone, I have a weird problem with Qt, using QLineEdit
here's a sample of my problem
from PySide2.QtWidgets import *
from PySide2.QtGui import *
from PySide2.QtCore import *
import sys
app = QApplication(sys.argv)
edit = QLineEdit()
window_type = Qt.WindowType.Tool|Qt.WindowType.FramelessWindowHint|Qt.WindowType.WindowStaysOnTopHint
edit.setWindowFlags(window_type) # comment this line and everything is working
edit.show()
QObject.connect(edit, SIGNAL('editingFinished()'), edit, SLOT('deleteLater()'))
QObject.connect(edit, SIGNAL('editingFinished()'), app, SLOT('quit()'))
QTimer.singleShot(500, edit, SLOT('setFocus()'))
app.exec_()
the goal is to create a "free" (as in without parents) lineedit, and set the focus on it
I've tried things, but it looks like it can't be done with those special windows flags I'm setting
any idea ?
nimble lava
anyone able to troubleshoot with me? I don't understand why the movement in case of an event is this wonky despite it working just fine outside of my event loop
the lower part just makes the first piece go to every set of coordinates I defined as a tile, which works just fine
but my event movement just goes bananas for some reason
mighty frigate
(I "solved" my problem... rather than making a parentless lineedit, I added it to the app scene (which is an openGL scene). A bit tedious but it's working)
manic lodge
how do i get the time since it was first run
karmic shoal
you could use the datetime module to get the time as soon as you launch the app, then along the road you can calculate the time difference
sinful oasis
@karmic shoal are you familiar with tkinter ?
@karmic shoal are you familiar with tkinter ?
because i need to send the row of a button when pressing the button and i can't figure it out
karmic shoal
what have you tried so far?
sinful oasis
in the command part i tried lambda c=self.x:fucntiontobecalled(c)
tried to put the row in a list but i can't get the position of the good row
karmic shoal
can you post your code?
manic lodge
Right, trying to use datetime in pygame

@manic lodge your question was how do i get the time since it was first run
karmic shoal
I'm not familiar with pygame

@karmic shoal Your eval job has completed.

Any ideas @karmic shoal
karmic shoal
well I'm looking at it, and can't you pass whatever row you use when calling grid to the function in the lambda when binding the button?
sinful oasis
I can pass it but the variable changes each time (self. x +=1)
