Qt Paint Outside Paintevent at Amelie Bruce blog

Qt Paint Outside Paintevent. In qt3 3.3 i created a widget that had a standard paintevent, but also had an enterevent and leaveevent which changed the way the widget. Qpainter provides standard functions to draw points, lines, ellipses, arcs, bézier curves, and other primitives. Just paint to a qpixmap, and copy it to the real widget in the paintevent. The short answer is, you can’t — qt does not work that way. If your painting is static you can paint onto a qpixmap once and then, in your paintevent, you just paint that pixmap. Paint events are sent to widgets that need to update themselves, for instance when part of a widget is exposed because a covering widget was moved. From the documentation, i had found out a way to implement this feature. You shouldn't try to workaround it. The way is delegate emit a signal to tell list view to update. This is the only standard way. Paint events are sent to widgets that need to update themselves, for instance when part of a widget is exposed because a covering widget was moved. If you’re outside of paintevent () and you want to repaint your widget, what you need to do.
