Unsolved i want to call an auto call event which gets calls automatically after any control or widget get changed
-
Here i am using QGraphicsview control to add line .
line is added using QGraphicsLine through mouse move event, and press event,
but i want to do operation after any image is inserted into view contrl.
in Windows Visual Studio System paint event is called every time whenever any control has been changed -
Hi and welcome to devnet,
Since you are inserting the image yourself, why not start something from the function where you add the image to the QGraphicsView ?

@Vijay-Lamkane
for a system (Qt-wise) wide notification you can create your own custom event and post it to the QApplication.
Then any other object/widget can read these events (by installing an event filter on the QApplication instance)
