MouseWheel method in wxPython?

Hello,

Anyone knows why there is no method for MouseWheel in wxPython? The equivalent to

MiddleDown(self) but for the mouse wheel. Note I’m not looking for EVT_MOUSEWHEEL. I want to use the method for a motion event such as

if MiddleDown():

DoSomething()

Also I tried this but it does not work

if (evt.GetWheelRotation() > 0):

DoSomething()

Any alternative?

What happens if you try EVT_MOUSE_AUX1_DOWN or
EVT_MOUSE_AUX2_DOWN?

On MacOS, Windows and Ubuntu i use EVT_MOTION for tracking movement for any button.
self.CaptureMouse() can help too.

Hi Guys,

Thanks for the feedback. I found a solution to do dynamic zoom through EVT_MOUSEWHEEL and GetWheelRotation. My example looks like this

def OnWheelScroll(self, evt):

if evt.GetWheelRotation() > 0:

zoom_factor = 2

else:

zoom_factor = 0.5

self._display.Repaint()

self._display.ZoomFactor(zoom_factor)
