I'll test IDE integration and let you know.

The problem is that:

1) the OnItemSelected, which would have been the logical choice, doesn't 
appear to work (for the vsIcon mode) with some popular widgetsets (I 
don't remember which ones, but a couple among gtk2, win32 and Qt)

2) OnClick and OnDoubleClick do not provide you neither the ListView 
Item nor the mouse position: you know only that the full window has been 
clicked somewhere. Therefore one is forced to use an event which 
provides mouse position. The choice is then between MouseDown and 
MouseUp. I picked up MouseUp because it simulates the behavior of 
OnClick (which is actually triggered when mouse is released.

I've been fighting with ListView when working on editortoolbar and I 
learned that it's a sort of wild beast, which nobody has succeeded in 
taming up to now. It almost never does what's expected to do.
That's why I had tried to avoid it. Code for positioning widdegts on a 
window is a child's play, with respect with events which do not occur, 
or which occur in reverse order, or things like that...

Project planning question: when it's 90% done, are we halfway or not yet?
