Unable to handle WindowStateChange events

[TheRonin]

Hi there!

I'm sitting on linux and find myself needing to keep the user from changing the window state of a dialog. To start off with, i tried setting the window flags such that no minimize or maximize buttons would be shown. This failed since for some reason, my window manager insists on drawing at least a maximize button and depending on my system settings, a 'shade' button as well.

My next stop was to accept the minimize or maximize buttons being shown, but ignore the WindowStateChange events. So i implemented QDialog::changeEvent(QEvent*) in hopes of being able to ignore the appropriate events as they come in:

void MyDialog::changeEvent(QEvent* event)
{
    if (event->type() == QEvent::WindowStateChange){
        cout << "window state change event! window state:" << windowState() << endl;
        //should i perhaps do event->accept() or event->ignore() here?
    }else{
        QDialog::changeEvent(event);
    }
 
}

void MyDialog::changeEvent(QEvent* event)
{
    if (event->type() == QEvent::WindowStateChange){
        cout << "window state change event! window state:" << windowState() << endl;
        //should i perhaps do event->accept() or event->ignore() here?
    }else{
        QDialog::changeEvent(event);
    }

}

To copy to clipboard, switch view to plain text mode 

Unfortunately, this doesn't work either. The events are still getting through and the window is still being minimized and maximized. Am i completely at the mercy of the window manager or is there some way, any way, of solving this problem!?

thanks in advance!
