Question

I have a QPushButton with an image that has two areas that I want to handle differently when clicked. Due to the positioning on the image, I cannot really use separate buttons for the two images.

What I’d like to do is, in the slot where I am handling the click, have it check the coordinates of the click to determine which area was clicked.

Is there a way to access this?

This is what first comes to mind. It should work, although there may be a simpler way:

• Create your own class that derives from QPushButton.
• Override the necessary mouse events (mousePressEvent and mouseReleaseEvent) and, before calling the base class implementation, set a property in your object using setProperty with the position of the mouse click. (The position is available from the event parameter.)
• In the slot handling the event, use sender() to get the button, and read the property using property().

If you don’t need to treat your object as the base class (QPushButton*) you could just create a new signal that includes the mouse event and attach that to your slot. Then you wouldn’t need the property at all.
