Qt Set Background Image 3 methods (simple, but worthy of careful understanding)

Method 1. setstylsheet{"Qdialog{background-image:url ()"}}//Using stylesheet This method has the advantage that inheriting its dialog automatically sets the background, such as replacing the skin is a good choice
Method 2. Qpalette Pal;

Pal.setbrush (Qpalette::background,qbrush (Qpixmap (")));
This->setpalette (PAL);
Method 3: In the PaintEvent (Qpaintevent *) Event//This is used for a variety of custom controls
qpainter painter (this);
Painter.drawpixmap (Rect (), qpixmap&);
