Prevent minimize window when click Show Desktop

[stucremon]

I have tried to make a window that continue show up after Show Desktop clicked.
I have tried overload changeEvent function:
@void mainwindow::changeEvent(QEvent *event)
{
if(event->type()==QEvent::WindowStateChange)
{
event->accept();
showNormal();
raise();
}
else
QWidget::changeEvent(event);
}@
But this doesnt work
So, how can I do that?

i'm not sure it thats possible at all...
Do you mean for example in windows when you press WINDOWS-KEY+D?

You can also try to remove the Qt::WindowMinimizeButtonHint from the window-widget's window flags property. At least this disables the widnow getting minimized by menu or the window button.

I don't know how to do it, but it's not a regular 'minimize'. The window seems to retain it's size, but is hidden somehow. I suspect you would have to dig into the windows API to solve this one.

From a user's point of view, I would be very annoyed by an application that does not disappear on Windows-D, but that's just on a personal note.
