Do you mean QT from Trolltech (the GUI library), or QuickTime from Apple?

Your question is far too vague to be answered without a huge essay about different development approaches and comparisons of features sets of different GUI frameworks and so on.

Perhaps you could come up with some more specific questions?

I did some programming in QT some time ago and I'm about to start a new attempt. What I didn't like about it was that after a while I had a huge mess with all the connections between the buttons of the applications and I needed as well a while until I got it working with Kdevelop. This time I'll try to use it with the Eclipse Europa C++ IDE - hope it will work better... .

You're welcome! I've been using it yesterday and after installing the plugin and restarting the app (you never know) I had to re-select my default workspace (under "File"). Everything was ok (fantastic how it is incorporated into Eclipse) until I started fiddling around with the widgets (following the guide in the qt-cheatsheets, just to warm-up). Each time I wanted to change the properties of the widgets (size, name, etc...) eclipse was hanging for ~30 seconds, but I didn't see any cpu usage or disk activity, so I currently don't know why that is happening.
I am now installing it into a virtual Xen OS running on 64-bit (yesterday I installed it on my 32-bit Pentium-m notebook) and will see if that is still happening... .

Mmmhh, it looks like you're right. After spending 14 hours installing Xen, a virtual OS, QT and Eclipse I tried it out and I didn't notice problems with speed on the remote machine nor on my notebook since I rebooted it - sniff... . But well, it works - nice.

It still gets slow and it even won't let me change the properties of the widgets, but I didn't fully understand under which conditions it starts happening. Perhaps when you start editing the .h / .cpp code. I'm now using "designer", which is delivered with the QT installation, in order to edit the forms - no problems using it.

I'm programming Qt with Python. My system is far from cutting edge (P4, 512MB RAM) and using Eclipse with PyDev was testing my patience: it locked up or crashed often. Uhmmm, OK, so I'm using a Java IDE with a C++ based toolkit and a Python language plug-in, maybe that's stretching things too much. With KDevelop however things run excellent.
I think you can avoid most of the mess with Qt only by developing the screens and dialogs with QtDesigner. Resist the temptation to code manually what can be made through the designer!
