repaint()¶ Repaint the view content, using the View::painter.
Re-paint the view content. This method should be called then the view content has changed. You can call this method directly, but it might cause graphics artifacts because the display is not double buffered. Instead you should schedule a repaint by calling the scheduleRepaint() method. This method will schedule the repaint, right after the next display update.
The display system will not schedule any repaints automatically. The view does not contain any state information, so you or other classes utilizing view must schedule repaints.
In subclasses of View, this method must be overwritten.
