Hi, Guys could any one point it out to me a link to web page where I can find hierarchy of classes in Qt prefferably as a diagram (something in UML style)?

I want to create an event in one Qt application that can be picked up by a seperate Qt application running at the same time. The normal sendevent function requires you to name the object which will receive it but I can't use that, I want it to be like a keyboard press event which filters through any open programs in the OS. Does anyone k...

Hello everyone, I am using the Qt Graphics View framework to create a scene and attach multiple views to the same scene, where these views render a 3D openscenegraph scene as background and the 2D drawings are kind of overlays.

Hi, my question is about Qt and its QAbstractItemModel. I have a map of strings and doubles (std::map<stringclass, double>) which I would like to present in a Qt widget. While I could use QTableView for that, I would like to exploit the fact that the keys of the map are of form "abc.def.ghi" where there can be multiple strings that c...

The QTableWdiget is fabulous for simple grid displays. Changing colors, fonts, etc is straightforward. However, I did not manage to give the grid a 'tighter' look with less vertical whitespace. I see that the Qt documentation talks (eg here) about margin border padding around widgets, but when I set these I only get changes aroun...

Strange bug with a Qt dialog ( Qt4.6/windows) If the dialog is started from MainWindow (from a toolbar/or menu action) and it is modal none of the text boxes will accept any edits. Other controls (drop down, buttons etc) all work. If I make the dialog non-modal, with show() rather than exec(), it works perfectly! Anyone come across a...

I'm using stripped down as much as possible configuration of Qt but now I need to use the dbus and can't figure out what I need to include to be able to use it? There doesnt seem to be anything obvious to me using the qconfig tool. The errors I get at the moment when making are: qdbus_symbols.cpp:53: error: expected initializer before ‘...
Several examples on trolltech use QWidget rather than a QMainWindow as the main window for simple Qt applications. Now I need just a simple window with a single content widget (QGlWidget) that covers the entire client area. However, when I show a QWidget window with a single content window it automatically resizes itself to be tiny. I...
