Hidiho,
first of all, I wanna thank you yop for your efforts. The Plugin works quite well for me now, although I had a bit of a hassle.(next time, read wiki first ^^)
Anyway, couldn't we just add a new project template which sets all the configs we need for workbench? Would ease up the process for Qt and c::b beginners. Also, if it's possible, it would be nice if the generated ui_*.h and moc_*.h could be added automatically.
oh, last but not least. I've got a little bug. I'm on a resolution of 1280x1024 and when I try to access the qtworkbench tab in the project properties, it won't fit the standard window size of the dialog, i.e. it doesn't resize that well ^^ So I almost crawled up the wall wondering where to activate the plugin, because the damn checkbox wasn't visible. I'm on c::b release 8.02. Don't know if this is a bug or an easter feature ^^
Apart from that, the Plugin really rocks. Keep up the good work.
