Description
if an update for n≥2 rects in a window is requested, seemingly the background is erased for the enclosing rectange but updates are clipped to the actual region only.
attached images:
grey: the lower80% is a terminal widget which does precise update(…) calls where characters are modified.
the window background is painted with
void MemoryInspector::paintEvent(QPaintEvent*)
the terminal widget repaints with:
void SimpleTerminal::paintEvent(QPaintEvent*)
note that the standard GUI widgets at the top are also cleared but not repainted.
orange: here are some QLineEdits widgets on a window. They are updated on a timer which mostly updates only some widgets because mostly only some values change. seemingly unmodified (and not updating) widgets between updated widgets are cleared and not repainted.
the window background is painted with:
void Inspector::paintEvent(QPaintEvent*)
the QLineEdits are not subclassed.
