This is probably an issue in C++ Qt but I can't test it.

Minimise a widget then hover over it in the task bar and click the cross without maximising it.

It will call hideEvent twice without a showEvent call.

I was expecting every hideEvent call to be paired with a showEvent. Is this not the case?

Steps:

1) Run the python file attached

2) Minimise the window

3) Hover over the application in the task bar and click the cross.

The console should look like this

show
hide
hide
