Hello,
I am trying to handle single and double-click events differently in a
QToolButton.
From what I have read in forums, Qt does not filter out single click
events when a double click occurs, in other words there will always be a
mousePressEvent emitted even if it's actually a double-click. The
recommended approach in C++ appears to be launching a timer and
deferring single click handling.
a) If there is a better approach, please let me know!
b) I tried the implementation below, but in the timerExpired function I
get the dreaded "Internal C++ object (PySide2.QtGui.QMouseEvent) already
deleted" error. I guess storing it in a member variable is insufficient?
(snip)
I would rather base the implementation on the 'doubleClickInterval()'
for the QTimer, and use a boolean variable to handle when it's
single or double click, so you can then implement
'mouseDoubleClickEvent()'.
You can check an implementation here:

Not sure if it's better than your approach,
but at least it's simpler IMHO.
Let me know if that's enough, otherwise, we can try to address the
C++ issues you are having in your code.
Cheers
