Hello Chris,
Thank you for your answer.
Try self.Canvas.CaptureMouse()
>
It works, indeed ! (see attachment)
(I also get Traceback like this :, but maybe this is not very important?,
it works anyway...
Traceback (most recent call last):
File "C:\Users\Silk\Desktop\MultiHitDemo(1).py", line 76, in OnUp
self.Canvas.ReleaseMouse()
File "C:\ProgramData\Anaconda\lib\site-packages\wx-3.0-msw\wx\_core.py",
line 10649, in ReleaseMouse
return _core_.Window_ReleaseMouse(*args, **kwargs)
wx._core.PyAssertionError: C++ assertion "!wxMouseCapture::stack.empty()"
failed at ..\..\src\common\wincmn.cpp(3319) in
wxWindowBase::ReleaseMouse(): Releasing mouse capture but capture stack
empty?
)

That's right, I forgot all these things ! Now everything is clear...
