Qt will ask immediately that it be shown. When the user sees it, that's 
another story. Please consult your window manager for this.

Note that the drawing of the contents of this widget will only happen once the 
window manager tells Qt that the widget is shown and needs repainting. That 
can happen two years after you called show().
