wxPython gridbagsizer颜色

Question

我正在测试一个应用程序。现在我想在中间面板周围有一个漂亮的边框，所以它嵌入到另一个面板中。但是，当我想在其中添加一个 gridbagsize 并将静态文本组件放入其中时，它会获得主面板的颜色，而不是中间面板的颜色。显然我做错了什么......

代码：

    #Parent panel
    pnl = wx.Panel(self)
    pnl.SetBackgroundColour('#4f5049')

    vbox = wx.BoxSizer(wx.VERTICAL)

    midPan = wx.Panel(pnl)
    midPan.SetBackgroundColour('#ededed')

    vbox.Add(midPan,wx.ID_ANY, wx.EXPAND |wx.ALL, 20)

    sizer = wx.GridBagSizer(10,5)
    #sizer.
    st1=wx.StaticText(pnl,label='TEST')
    sizer.Add(st1, pos=(1,1),flag=wx.ALL,border=5)
    midPan.SetSizer(sizer)
    #vbox.Add(sizer,wx.ID_ANY, wx.EXPAND |wx.ALL, 0)
    #draw application       
    pnl.SetSizer(vbox)

如您所见，似乎将 sizer 添加到 pnl 而不是 midPan... 我做错了什么？

您将静态文本定义为 pnl 的子项而不是 midPan

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, id=wx.ID_ANY, title="", size=(360,100)):
        super(MyFrame, self).__init__(parent, id, title, size)
        pnl = wx.Panel(self)
        pnl.SetBackgroundColour('#4f5049')

        vbox = wx.BoxSizer(wx.VERTICAL)

        midPan = wx.Panel(pnl)
        midPan.SetBackgroundColour('green')

        vbox.Add(midPan,wx.ID_ANY, wx.EXPAND |wx.ALL, 20)

        sizer = wx.GridBagSizer(10,5)
        st1=wx.StaticText(midPan,label='Black on green')
        st2=wx.StaticText(midPan,label='White on green')
        st2.SetForegroundColour('white')
        st3=wx.StaticText(midPan)
        st3.SetLabelMarkup("<span foreground='black' background='red'>Black on red</span>")
        st4=wx.StaticText(midPan)
        st4.SetLabelMarkup("<span foreground='white' background='red'>White on red</span>")

        sizer.Add(st1, pos=(1,1),flag=wx.ALL,border=5)
        sizer.Add(st2, pos=(2,2),flag=wx.ALL,border=5)
        sizer.Add(st3, pos=(3,3),flag=wx.ALL,border=5)
        sizer.Add(st4, pos=(4,1),flag=wx.ALL,border=5)

        midPan.SetSizer(sizer)
        pnl.SetSizer(vbox)
        self.Show()

if __name__ == "__main__":
    app = wx.App()
    frame = MyFrame(None,title="The Main Frame")
    app.MainLoop()
