Why doesn't this work (wxpython/color dialog)

class iFrame(wx.Frame):
    def __init__(blah blah blah):  
        wx.Frame.__init.__(blah blah blah)  

        self.panel = wx.Panel(self, -1)  
        self.panel.SetBackgroundColour((I put a random RGB here for test purposes))  

        c_color = wx.Button(self.panel, -1, 'Press To Change Color')  
        c_color.Bind(wx.EVT_BUTTON, self.OnCC)  

    def OnCC(self, evt):
        dlg = wx.ColourDialog().SetChooseFull(1)  
        if dlg.ShowModal() == wx.ID_OK:  
            data = dlg.GetColourData()  
            color = data.Colour  
            print (color) # I did this just to test it was returning a RGB
            self.panel.SetBackgroundColour(color)  
        dlg.Destroy()  

What I've tried to do was link a button to a color dialog, store the RGB in a variable and use it to set the panel's background color...I've tested almost all of this, I've inserted the returned RGB开发者_运维百科 directly into the self.panel itself and it works, so why doesn't it work when I use it within this method

The line dlg = wx.ColourDialog().SetChooseFull(1) seems like a bug -- isn't SetChooseFull a method on wx.ColourData?

I made a few changes to get it working and commented the code to illustrate:

def OnCC(self, evt):
    data = wx.ColourData()
    data.SetChooseFull(True)

    # set the first custom color (index 0)
    data.SetCustomColour(0, (255, 170, 128))
    # set indexes 1-N here if you like.

    # set the default color in the chooser
    data.SetColour(wx.Colour(128, 255, 170))

    # construct the chooser
    dlg = wx.ColourDialog(self, data)

    if dlg.ShowModal() == wx.ID_OK:
        # set the panel background color
        color = dlg.GetColourData().Colour
        self.panel.SetBackgroundColour(color)
    dlg.Destroy()

The data.SetCustomColor(index, color) populates the N custom colors in the dialog. I've circled the one at index 0 below:
