Question

我构建了一个wx.Dialog，其中一些wx.Radiobox需要验证。如果用户没有做出选择，验证者将不会返回True并弹出wx.MessageBox告诉用户您应该选择的内容。同时，背景颜色应该变为粉红色。

这里的问题是当使用RadioBox.SetBackgroundColour("pink")时，RadioBox的标签文字的背景颜色变为粉红色，这是完全正常的，但RadioButton的标签文字的背景颜色赢了＆＃39 ; t改变直到鼠标经过。

我想知道为什么会这样以及如何解决这个问题。我查了官方文档并用Google搜索，但一无所获。有人有想法吗？

平台是win8.1x64和python 2.7.3以及wxpython 2.8.12.1。对于使用Psychopy独立包，python和wxpython的版本都很旧。

对话如下，非常简单：

class Dlg(wx.Dialog):
    """A simple dialogue box."""

    def __init__(self):
        global app
        app = wx.PySimpleApp()
        wx.Dialog.__init__(self, None,-1)

        self.sizer = wx.FlexGridSizer(cols=1)

    def show(self, cancelBTN=False):
        """Show a dialog with 2 RadioBox"""

        # add two RadioBox

        RadioBox1 = wx.RadioBox(self, -1, label="Wierd color", choices=["", "choice A", "choice B"], validator=RadioObjectValidator())
        RadioBox2 = wx.RadioBox(self, -1, label="Wierd color", choices=["", "choice A", "choice B"], validator=RadioObjectValidator())
        RadioBox1.ShowItem(0, show=False)  # Hide the first choice
        RadioBox2.ShowItem(0, show=False)  # Hide the first choice

        RadioBox1.GetValue = RadioBox1.GetStringSelection
        RadioBox2.GetValue = RadioBox2.GetStringSelection
        self.sizer.Add(RadioBox1, 1, wx.ALIGN_LEFT)
        self.sizer.Add(RadioBox2, 1, wx.ALIGN_LEFT)

        # add buttons for OK

        self.sizer.Add(wx.Button(self, wx.ID_OK), 1, flag=wx.ALIGN_RIGHT)

        self.SetSizerAndFit(self.sizer)

        if self.ShowModal() == wx.ID_OK:
            pass
            # do something

        self.Destroy()

和Validator一样：

class RadioObjectValidator(wx.PyValidator):
    """ This validator is used to ensure that the user has entered something
        into the text object editor dialog's text field.
    """
    def __init__(self):
        """ Standard constructor.
        """
        wx.PyValidator.__init__(self)

    def Clone(self):
        """ Standard cloner.

            Note that every validator must implement the Clone() method.
        """
        return RadioObjectValidator()

    def Validate(self, win):
        """ Validate the contents of the given RadioBox control.
        """
        RadioBox = self.GetWindow()
        choice = RadioBox.GetValue()

        if not choice:
            wx.MessageBox(u'Choose something please', u'info', wx.OK | wx.ICON_EXCLAMATION)
            RadioBox.SetBackgroundColour("pink")
            RadioBox.SetFocus()
            RadioBox.Refresh()
            return False
        else:
            RadioBox.SetBackgroundColour(
                wx.SystemSettings_GetColour(wx.SYS_COLOUR_WINDOW))
            RadioBox.Refresh()
            return True

    def TransferToWindow(self):
        """ Transfer data from validator to window.

            The default implementation returns False, indicating that an error
            occurred.  We simply return True, as we don't do any data transfer.
        """
        return True  # Prevent wxDialog from complaining.

    def TransferFromWindow(self):
        """ Transfer data from window to validator.

            The default implementation returns False, indicating that an error
            occurred.  We simply return True, as we don't do any data transfer.
        """
        return True  # Prevent wxDialog from complaining.

就这样运行：

if __name__ == "__main__":
    test = Dlg()
    test.show()

嗯，这是wxpython2.8.12.1中的一个错误，已在wxpython3.0.0.0中修复，感谢@GreenAsJade提醒。

wx.Radiobox.SetBackgroundColour（＆＃34; pink＆＃34;）不会改变RadioButton的颜色，直到鼠标经过
