交换图像时如何将JLabel从一个面板复制到另一个面板？

Question

I have the following layout...

What I would like to do ideally is, when a user clicks on a JLabel in the scrolling panel on the bottom right, attach a different version of the image (one without the costs and name) to the mouse cursor. Then when the user clicks inside the giant floor plan panel, it places a copy of a JLabel using the swapped image each time they click. When another label is selected the same thing happens. When they push the selection button (Hand Icon) or press ESC the label is unselected.

Here is the code I currently have unmodified...

I don't have much experience at all with GUIs in general so it's a wonder I got this far. Has anyone ever worked on something like this? Any suggestions how to make it work?

Answer 1

I think it's answer for you.

1) Get all your Images and cut from they cost and name data.

2) Add your components with help of LayoutManager, I think GridBagLayout is suitable for that purpose.

3) Add your Image with help of(JLabel) then add JLabel with name property under the first and next add JLabel with cost.

If you do all in that way you can drag only Images without additional information, it solve problem with different images for one Entity.

As recommendation:

1) Change your mouseClicked method in next way:

public void mouseClicked(MouseEvent e) {
    removeFocus();
    ((RLabel)e.getSource()).setBorder(BorderFactory.createLineBorder(Color.black, 3));
    ((RLabel)e.getSource()).setFocus(true);
}

It clears method from duplication code.

2) instead of using setBounds() method use LayoutManager it do all work with component size.

3) Never do that setLayout(null);

4) Split your constructor method for some simple and clear methods. It's really looks awful.
