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!

You can tell the dialog to remain fixed in size, for instance using QLayout::sizeConstraint property.
