Wait, Qt 4.6 *finally* has support for freedesktop.org-compliant icon loading? That was really the only major annoyance I had with Qt, so I'm glad they finally took care of that

.
Yes, it does

(I thought that's where you took this code from...)
However, until 4.6 is more standard on released desktops, I'll probably have to stick with qtIconLoader.
The next round of major distribution upgrades should bring Qt 4.6 to many people's system (speaking for Linux - Windows and Mac users have to manually install Qt anyway), so I'd say in 3 to 5 months Qt 4.6 should be spread fairly well.
Qt 4.5 compatibility now in trunk. Still no icons in Qt 4.5, but I'll deal with that another day.
Thanks, I can confirm that

. I attached a patch adding tooltips to the three buttons that are labelled with "..." only. At least, I think the third button is "Remove Object", it doesn't seem to do anything

. Speaking of which, is there any way to remove a layer?
