I am a new Java user and have been working on a password manager project. I have completed functionality for reading data and storing it, but I need help creating my output window that displays all the user info.

I am mainly struggling with moving a text area. I experimented with creating rigid areas but I am at a loss and just need some guidance. My title label is supposed to go above my text area.

Attached is an image of my current output window(1st), an image of my final goal example output window(2nd), and the snippet of code for the output window creation(3rd).

Which part of that is the problem?

Need to move the text area below the Title Label. Here is the current output window:

#

#

Using a rigid area I can move both together lower on the screen, but I want to have the JLabel (Company Username Pass) above the text area.

With title label, you mean the Company/Username/Passwprd line?

#

Yes

#

Sorry for the confusion there.

Where did you add textArea to the panel?

#

oh, via scroll

#

        panel.add(scroll);
        panel.add(titleLabel);

#

maybe try reversing the order of these operations?

#

That fixed it! I was confused why panel.add(textArea); broke everything. I didn't know that scroll was connected to the textArea. So I only need to add scroll instead of both things.

#

#

Last issue I have is the scrollbar. I want the text area to stay at a certain size and the scrollbar display the data at the bottom. Here is an image of my professor's example:

#

Here is where mine is at:

maybe try restricting the size of the scroll pane?

#

I didn't even know you could do that.

#

maybe using scroll.setPreferredSize: https://docs.oracle.com/en/java/javase/20/docs/api/java.desktop/javax/swing/JComponent.html#setPreferredSize(java.awt.Dimension)

JComponent (Java SE 20 & JDK 20)

declaration: module: java.desktop, package: javax.swing, class: JComponent

onyx basin Apr 12, 2023, 5:31 PM
