I am developing an application that need to draw some lines (NACA profiles in
fact) using pyqt and qt-designer.
I begin using a PixmapLabel for the drawing area, now (after some research on
google) i use a frame.
As I find in the documentation, to draw my polyline I implemented the
paintEvent method and this is ok.
The problem is when I resize the window or the program goes under another
In the first case, i try to implement also the resizeEvent but the result is
that I have a flickering update and sometimes after a resize I don't see
nothing. In the second case the PixmapLabel and also the frame where not
repainted when the application get the focus, since the paintEvent where not
called. What signal I must intercept ? Any suggetion ?
thanks in advance.
