wx._core.wxAssertionError: C++ assertion "!(flags & wxALIGN_CENTRE_HORIZONTAL)" failed

Hi there, and thanks for your nice work.

But i got the "wx._core.wxAssertionError: C++ assertion "!(flags & wxALIGN_CENTRE_HORIZONTAL)" failed" error, as following:

E:\RoSeMotion>python.exe app/main.py

i‘ve installed the "Leap_Motion_4.0.0.exe", python3.7.2 and pluged the leap motion device.

This seems to be unrelated to Leap Motion or Python version. Looks like an error in Gooey. Which Gooey version are you using?

pip show gooey

RoSeMotion/requirements.txt

Line 10 in 4ef7997

Gooey==1.0.8

[seanschneeweiss]

You can also try Leap Motion 5.3.1 Gemini and Python 3.9
https://github.com/seanschneeweiss/RoSeMotion/tree/gemini-5.3.1/app/resources/LeapSDK/v53_python39
(this is unrelated to you issue, just a notice that you can use a newer Leap Motion version than 4.0.0)

[seanschneeweiss]

Seems to be a known issue from Gooey: chriskiehl/Gooey#549
You can try to update Gooey to 1.0.8.1 pip install gooey==1.0.8.1 or downgrade WxPython pip install wxPython==4.0.7

pip install gooey==1.0.8.1 does not work,
pip install wxPython==4.0.7 makes the app running, however, when i start to record, the error dialog is:

Uh oh! Looks like there was a problem. 
Copy the text from the status window to let your developer know what went wrong.


[OK]

The status is:

Looks like you have two instances of the Visualizer open at once? Best would be to close all of them.
But good to know, that this is something that should be fixed.

Error comes from this part:

RoSeMotion/app/GuiControl.py

Lines 12 to 24 in 4ef7997

	def set_windows_record(self):
	self.visualizer = Application().start(r"C:\Program Files\Leap Motion\Core Services\Visualizer.exe")
	self.visualizer_dlg = self.visualizer.window()
	self.recorder = Application().connect(class_name="wxWindowNR")
	self.recorder_dlg = self.recorder.window()
	visualizer_dlg = self.visualizer_dlg
	recorder_dlg = self.recorder_dlg
	# toggle off the help menu
	visualizer_dlg.set_keyboard_focus().send_keystrokes("h---f")
	# get maximum screen size
