Detect mouse doubleclick

[Arkie]

A quick way to find out if a user made a doubleclick with their mouse is to implement a MouseListener in the application and add this in your MouseClicked() method

Code

GeSHi (java):
	public void mouseClicked(MouseEvent e) {
		doubleClicked = doubleClicked+1;		
		if(doubleClicked ==2){
			System.out.println("double clicked");
			doubleClicked =  0;
		}

However, this will always register the 2nd click as the doubleclick and you don't want that, i've rewritten my code so that the doubleclick only shows up when the mouse is in the same position as before and the user has clicked twice within the same position.

Code

GeSHi (java):
