Running Urho3D and Qt from main

I am using the Urho3D engine with Qt for an application. The problem is that both Urho3D and QApplication require to be ran from main(). For now I am using it in separate processes but IPC makes it complicated. Is there any way to solve this issue? Thanks

My platform is Urho3D 1.5, Qt 4.71 and Windows 7 x64 and VS2015 (C++)

Solution

  • So the answer is quite simple. Instead of running QApplication by calling

    app->exec();

    it is needed to manually and regularily call this from your main loop:

    app->processEvents();

    This will take care that all events used by Qt are processed and QApplication will respond accordingly. Example:

    #include <QApplication>
#include <awidget.h>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    bool shallrun = true;
    aWidget *widget = new aWidget();
    widget->show();

    while (shallrun)
    {
       app->processEvents();
       ...
    }

    ...
}
