Title: QT, anyone has ever played around with it?
Post by: Zaeranos on November 26, 2010, 10:39:28 pm: Okay, just to point out I mean this QT => http://qt.nokia.com/

Now the question to why I am interested in it. For my master thesis project I need to work with and program for a tool the university is developing. It is a tool that eases prototyping with OpenCV. However it is build in Qt Creator and the Qt Library and Utilities. It is nice and very extensive. It offers platform independence. However it also makes it feel very a lot like Java. A shitload of new stuff on top of C++ original stuff with a shitload of new features, that are spread over a shitload of classes and thus a shitload of things to memorize. Oh yeah and a number of keywords.

Well, my problem is not the extra features, but it does get overwhelming with a lot to learn. So I wonder if anyone has experience with it and what you think of it.

It's kinda confusing at first, but once you understand how to connect signals and slots, you can build an app with "relative" ease.

I think it's a great framework.

also don't worry about the "stuff added on" it's VERY fast and moc does a heck of a job of translating everything before compile time. Yes the debug libraries are huge (QtGuid4.dll is > 100 MB) however the release runtimes are tiny offsetting this.

one tip i have is to RTFM, it's your holy bible of Qt, don't bother trying to remember anything, if your confused about something simply look it up. The documentation is extensive and covers almost everything (a few things are so simple it's not necessary to document them entirely)

My only gripe is the "custom" make file (the .pro) used by Qt Creator, it can be cumbersome and difficult to understand and is not documented well (yes I realize I just contradicted myself).

I know. It is the holy bible of almost anything. I am reading through the manual on-line and a book called C++ GUI Programming with Qt 4. Qt Creator is a nice IDE and with Qt Designer you can make very easy GUI's. But the guy that worked on the tool before me had some very advanced stuff in it and I have only a few weeks to get up to speed.

But is nice to know that there are a few I can call for help.

How is Qt's OpenGL options btw. The Qt creators themselves think it is good for making games, however other sources that I read state that it is not so great.
