Problem with the overlap between the background and a panel | Together Java | Page 1

in this code, "loginPanel" dont respect the dimensions i gave to it(300x450), but it fits in all the screen like the backgroundLabel.
so then the loginPanel goes to cover the background.
this is the code:

package gui;

import javax.swing.*;
import java.awt.*;

public class LoginGUI extends JFrame {

    private static JLabel backgroundLabel;
    public LoginGUI() {

        super("LoginApp2");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setLayout(new BorderLayout());
        setExtendedState(JFrame.MAXIMIZED_BOTH);
        backgroundImage();
        loginPanel();
    }

    public void backgroundImage() {
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        int width = (int) screenSize.getWidth();
        int height = (int) screenSize.getHeight();

        ImageIcon backgroundImage = new ImageIcon("C://Users//***//Downloads//Applicazione4BK.png");
        Image img = backgroundImage.getImage().getScaledInstance(width, height, Image.SCALE_DEFAULT);
        backgroundLabel = new JLabel(new ImageIcon(img));
        add(backgroundLabel, BorderLayout.CENTER);
    }

    public void loginPanel(){
        JPanel blurPanel = new JPanel();
        blurPanel.setPreferredSize(new Dimension(30, 50));
        blurPanel.setBackground(new Color(11, 192, 239, 0));
        add(blurPanel, BorderLayout.CENTER);
        
    }
}```

issue is that the "loginPanel" is not respecting the dimensions you have set for it (300x450) and instead it is fitting to the entire screen like the "backgroundLabel".

There could be a few reasons why this is happening. Here are some possible solutions:

Check if there are any constraints or autoresizing masks applied to the "loginPanel" that might be causing it to resize automatically. Make sure to remove any conflicting constraints or adjust the autoresizing masks accordingly.
Verify that you are setting the correct frame or bounds for the "loginPanel". Double-check your code to ensure that you are setting the dimensions correctly.
If you are using Auto Layout, make sure that you have set up the constraints properly for the "loginPanel". Check if there are any conflicting or ambiguous constraints that might be causing it to resize incorrectly.
If you are using a container view controller or embedding the "loginPanel" within another view, make sure that the container view's dimensions are also set correctly and not conflicting with the "loginPanel".
If none of these solutions work, try debugging by printing out the frame or bounds of both the "backgroundLabel" and "loginPanel" at different stages of your code execution. This can help identify any unexpected changes in their dimensions.

By troubleshooting these potential issues, you should be able to fix the problem with the overlap between the background and panel in your code.

Do you want the dimensions of it to be fixed?

woven oriole Jan 27, 2024, 1:52 PM

#

ye, i suppose that the dimensions i gave to loginPanel dont work coz it interfere with setExtendedState(JFrame.MAXIMIZED_BOTH)

eternal pagoda Jan 27, 2024, 1:53 PM

#

you can use setMaximumSize() then i would think

#

if you are ok with itt being fixed

#

or just setSize i guess

woven oriole Jan 27, 2024, 2:03 PM

#

i tried add that blurPanel.setMaximumSize(new Dimension(30, 50)); as u suggested. but it still does not work.

#

it still covers the entire screen, covering the background

eternal pagoda Jan 27, 2024, 2:09 PM

#

also with setSize()?

woven oriole Jan 27, 2024, 2:09 PM

#

as i said i think setExtendedState(JFrame.MAXIMIZED_BOTH) interfere with this loginPanel and create this problem. but i am not 100% sure

eternal pagoda Jan 27, 2024, 2:09 PM

#

i am not sure what that does

woven oriole Jan 27, 2024, 2:09 PM

#

eternal pagoda also with setSize()?

ye

eternal pagoda Jan 27, 2024, 2:12 PM

#

Just looked it up in the documentation, setExtendedState(JFrame.MAXIMIZED_BOTH) just maximizes your frames size

#

so im not sure what the problem is

#

ok.. hope some helper will find it

now the blurPanel appear but in the up-left side of the screen(it seems a default position). also if i wrote in center

woven oriole Jan 27, 2024, 5:51 PM

#

@eternal pagoda hey i found the solution

eternal pagoda Jan 27, 2024, 5:52 PM

#

nice

woven oriole Jan 27, 2024, 5:54 PM

#

basically in my code i wasnt giving the position of blurPanel in a own line, i just was doing a "add(blurPanel, BorderLayout.CENTER);"
and that made an infinitive recursion. so i added java blurPanel.setLocation( 480,100); with the "x" of of the number /2 of my pc screen and for the Y was a different thing

eternal pagoda nice

thats the result finaly

eternal pagoda Jan 27, 2024, 6:11 PM
