Java Swing/GUI Tutorial- Mouse Action Listeners - Creating MouseListeners

This tutorial will show you how to create MouseListeners. These can be used to detect when the mouse has been pressed down, clicked, released and others.

You can use MouseListeners to create many programs, for example, a program where the user draws his own shape on a canvas (like PCPaint). Hope you enjoy

Hi quick question, but it would be really nice if you can help -

What do I have to change, or add if I want to just keep on adding these little dots (as opposed to changing the position of the same dot), every time the mouse is clicked?

[MrJavaHelp]

remove line 14, super.paintComponent(g); in the paintComponent method in the "draw" class, and it will only add to the canvas every time the paint method is called instead of redrawing everything. Therefore, you can add circles to the canvas every time instead of drawing a new circle each time.

I like how you breathe directly into the microphone. It gives definition to your voice.

Problem I found: Sometimes when you "Click" and you have moved the mouse during the "Click" the dot will not appear. Simply changing mouseClicked(MouseEvent e) to mouseReleased(MouseEvent e) fixed this...in case anyone else had this problem..

draw is basically an extended JPanel class here right?

Firstly, thanks so much for these videos. You've helped me to no end. But could you possibly tell me the name of the program do you used to record this video?
