Hi,
I have done this, but the problem is twofold: this is not documented
anywhere that drag/drop doesn't work with checkboxes, and the only way
to do this is to do bad OO by cut/pasting the entire
_onMouseDown/_onMouseUp code minus the stopPropagation. If any change
were to be made to these methods, my code would need to be
re-cut/pasted, which makes it quite brittle, defeating one of the
primary purposes of OO.
One suggestion is that _onMouseDown/_onMouseUp add a 2nd optional
parameter like so:
_onMouseDown : function(e, stopPropagation)
{
if (!e.isLeftPressed()) {
return;
}
// Activate capturing if the button get a mouseout while
// the button is pressed.
this.capture();
this.removeState("abandoned");
this.addState("pressed");
if (null == stopPropagation) {
e.stopPropagation();
}
},
This would allow my derived class to simply do:
_onMouseDown : function(e)
{
this.base(arguments, e, true);
}
The second parameter would be null when called by the event callback.
Alternately, it would also work simply to add a restartPropagation()
method to the Event class. This way, my code could be:
_onMouseDown : function(e)
{
this.base(arguments, e);
e.restartPropagation();
}
Both of these solutions are better than what I am forced to do right
now, I hope that one will make it into qooxdoo 1.0.2 :)
Thanks,
Greg
