QT 4.2.3 Using GTK Widgets inside QT App

Hey guys,

I'm working on embedding Gecko in a QT app using GtkMozEmbed. With Qt 4.2 now using the glib event loop I want to integrate Gtk based widgets with my qt apps, in the same process. Has anyone had good success with that? Or do i still need to use QX11EmbedContainer? I have a simple app i found googling that uses both QT and Gtk in the same app. Showing a qt window with a button, that when clicked will launch a gtk window with a button, that goes back the other direction.

A simple question would be has anyone been able to do something like display a window with two buttons, one using QT and one using Gtk side by side in the initial qt window? Is there any particular technique to say, building a class extending QWidget that the gui components within are all built using Gtk, that would allow me to instantiate it in any other qt app and display it?

Thanks,
Chuck

I don't have an answer to your exact question but I do know that it is possible to draw GTK widgets using Qt -- that involves writing a GTK style which just calls the Qt widgets -- similarly perhaps it would be possible to have a Qt style which uses GTK widgets.

But I don't think that in a Qt application you can draw a GTK widget at all (directly I mean). The reason being that I don't think a GTK widget will submit to the control of a QLayout, or that a QLayout has the capability of handling a GTK widget. I do not think that a widget that a QLayout cannot handle can be drawn. But maybe you could directly write an X app which uses both the Qt and GTK widgets but then you would have to take care of layout etc yourself which would be a pain.

Of course, I'm not as knowledgeable as many people around here and my opinion may be wrong. I only answered because I noticed your question was unanswered for two days. I hope this helps at least a bit.
