How to find if image is clicked in JApplet?

Question

It is to support image dragging. How to find if an image is clicked in JApplet?

I'm sure there is an easy way to do this, but I've looked everywhere and cannot seem to find it.

Hopefully this thread can help you in finding, [How to get Mouse Clicks](http://stackoverflow.com/a/10345165/1057230) on `Image` — nIcE cOw, May 11 '12 at 02:49

Options:

Use a JLabel to hold the image, and give it a MouseListener. Simple.
Or create a JButtton and use the Image as the button's ImageIcon. Probably simpler.

It needs to be dragged... probably should have mentioned that – Ryley Matos May 11 '12 at 00:11

@RyleyMatos: then you'll probably want to go the JLabel/MouseAdapter route. Also, please let's try to avoid the changing requirements game here as it can get very frustrating. – Hovercraft Full Of Eels May 11 '12 at 00:15
How do I change paint the label to the JApplet with x y coordinates? – Ryley Matos May 12 '12 at 00:34
@RyleyMatos: give the container that holds the JLabel a null layout, and then set the JLabel's location via its `setLocation(int x, int y)` method. Then call `repaint()` on the container. – Hovercraft Full Of Eels May 12 '12 at 01:38

See the Drag and Drop and Data Transfer lesson of the tutorial.

If the purpose of the dragging is to change the order in a slideshow or similar, look to a JList. See setDragEnabled(true) & How to Use Lists for more details.

For the display component, I would recommend a JLabel as suggested by @Hover. JList uses a JLabel as the rendering component by default.
