Can LCL classes use Qt or Gtk2 as their back-end?
« on: May 23, 2013, 05:41:25 pm »
I am a total newbie, so this might be a silly question.

Can LCL classes use Qt or Gtk2 as their back-end?
What I have in mind is TMemo. I would like to use Qt as its back-end. Is it possible?

Yes, both are supported. For QT you also need a wrapper library. See:

Mostly Lazarus trunk and FPC 3.2 on Manjaro Linux 64-bit.

Hmm... could you be any clearer? I'm afraid is not a simple backend change that you mean. Do you want to mix the backend? If yes, then the answer is no (except for Custom Drawn Interface). LCL project must choose one backend for the whole project. Say, either GTK2 or Qt, but not both mixed under the same compilation.

No, I did not mean mixing the back-ends. I just wanted to know about which back-ends are supported, and I am happy to learn that both Qt and Gtk are supported.

Both our wiki and wikipedia already state the status of each widgetsets:
