MouseEvent.getClickCount() starts always with returning a 1.
I want to react differently on single or double clicks.
clearly I have to wait, to see what nr of clicks I get
my question is : does anyone know an elegant way to do this?
preferably in mousePressed()?
thanks,
peter
Try with one of these, ....
Option1
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2) {
System.out.println( " and it's a double click!");
}
else{
System.out.println( " and it's a simple click!");
}
}
//-//
Option2
public class MyMouseListener extends MouseAdapter {
public void mouseClicked(MouseEvent evt) {
if (evt.getClickCount() == 3) {
// triple-click
} else if (evt.getClickCount() == 2) {
// double-click
}
}
}

thanks for your response, but my problem is (seems to me) somewhat more complicated...
the returned click-count is clear, but my program puts a "point" somewhere (evt.getPoint()) on my Graphics-screen in reaction on 1 click.
this is my "normal" reaction, however, when I (later) detect double-clicking (meaning in my case that I want to select something (eg. a Shape) on the screen, I have to "undo" the setting from the "point" I just set.
Since all my screen-info is stored in a Vector this is a bit dumb.
It is not really a big problem, but my question remains the same :
how do I ignore click nr 1, when it turns out that a second one follows?

Probably the only way would be to schedule a timer at the first click. When a second click would occur, you cancel the timer and respond to the double-click.
Now the only question is, how long the timer should wait. Unfortunately you cannot retrieve the double-click speed from the OS, which would make your application inconsistent with the OS.
For usability i would recommend against it it. Since the usual double-click idiom is that the first click selects and the second(double-click) performs an action on the selection.
