Thread: close JPopupMenu after focus lost

not working

Please explain what that means?

When I compile and execute, it shows the trayicon. Then what do I need to do to see the problem?

I can't found the reason
pleas help

Sorry, I do not know what the problem is. Can you explain?

It works well in your class when I use mouse input and exit in your code to change the color of the menus, but it does not work when I use the codes in graphically
GUI in the form design menu. I have sent you my codes to try in previous posts
https://www.javaprogrammingforums.co...tml#post171238
this part of code don't work in gui (create new project-->create new jframe form-->use your code inside of them)

 
        Info.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                Info.setBackground(Color.GREEN);
            }
 
            public void mouseExited(java.awt.event.MouseEvent evt) {
                Info.setBackground(UIManager.getColor("control"));
            }
        });
        Exit.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                Exit.setBackground(Color.RED);
            }
 
            public void mouseExited(java.awt.event.MouseEvent evt) {
                Exit.setBackground(UIManager.getColor("control"));
            }
        });
 
        Open.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                Open.setBackground(Color.GREEN);
            }
 
            public void mouseExited(java.awt.event.MouseEvent evt) {
                Open.setBackground(UIManager.getColor("control"));
            }
        });

the color of the menus

Are you able to set the color of the menus at any time? Not just in a listener.

when i use in gui menus color It does not work in any way

Sorry, I do not know anything about the gui menus.

You need to make and post a small, complete program that compiles, executes and shows the problem.

i send small, complete program before

Are you able to set the original color of any of the menuitems BEFORE there is any mouse movement?
Try setting the color immediately after the call to setIcon.

I can not do anything with all those little pieces of code.
Did you see my question? What happens when you do this:

Try setting the color immediately after the call to setIcon.

working until remove this part from main

Then that is your solution.

What happened when you tried what I suggested?

Have you read the API documentation for the setBackground method to see if there is anything there that could help you?

I found solution in gui i must first setOpaque(true) and use like this

Info.setOpaque(true);
Open.setOpaque(true);
Exit.setOpaque(true);

Glad you found the solution.

Why don't you use graphic editors to find code errors? Creating buttons and changing their colors through Figma or WordPress is much easier. I have been working as a graphic designer for several years now and am moving more and more away from HTML and java towards simplification. Unfortunately, people increasingly need complex websites written in code.
However, I read that pop-ups have recently become relevant to attract the client's attention. I read about it in detail at https://promolayer.io/abandonment-prevention/. I plan to master this tool and implement it in my designers in the coming months. Do you think entrepreneurs will use this for their websites?
