Hi Stefan,
Thanks for reply. The problem is that I want exactly the item where
user clicked. You can see that selection is additive and I'm not
interested about it, so I need some mechanism to get item where user
clicked or null (of there is no item like scrollbar, etc).
The opener() was only my trying.
It took me about 2 hours and I have no solution. I can catch
contextmenu event, but I don't know how to translate coordinates to
the child widget. I looked at qooxdoo sources, but without success.
For example I have this code:
// I just see both, I don't know the right one, documentation
is very brief.
this.addListener("contextmenu", this._onContextMenu, this);
this.addListener("beforeContextmenuOpen", this._onContextMenu, this);
an in _onContextMenu() I want to get children based on event
coordinates, is this possible? Or more precisely, is this right
approach ?
