Fails to set bgcolor on StaticText on Raspberry pi (but not in Win10)

问题

I am trying to set the backgroundcolor of a StaticText in wxPython. I am using the method .SetBackgroundColour('Red'). That works as expected when I run my code on windows 10. However, when it runs on a Raspberry pi it fails to set the background colour (and the text alignment). Can someone help?

The code and a wheel file built on the raspberry for wxPython4.0.3 can be found on my Github: https://github.com/danneedebro/Problem_bgcolor_static_text

This is my simplified code:

Main.py

import wx


class Example(wx.Frame):
    def __init__(self, parent):
        super(Example, self).__init__(parent, title='Window', size=(300, 100))

        panel = wx.Panel(self)
        LblTextWithBgColor = wx.StaticText(panel, label='This text should have a red background', size=(250, 20), style=wx.ALIGN_CENTER)
        LblTextWithBgColor.SetForegroundColour('Green')
        LblTextWithBgColor.SetBackgroundColour('Red')
        self.Show()


app = wx.App()
Example(None)
app.MainLoop()

回答1:

You cannot set the background color of wx.StaticText in GTK. The label is just drawn on the parent window, which prevents you from doing much of anything with the widget. This is documented in a non-obvious location:

• https://wxpython.org/Phoenix/docs/html/wx.lib.stattext.html

However you can use the wx.lib.stattext instead as it is a generic widget that should work the same way on all platforms.
