为什么这不起作用（wxpython/颜色对话框）

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()

我尝试做的是将按钮链接到颜色对话框，将 RGB 存储在变量中并使用它来设置面板的背景颜色...我已经测试了几乎所有这些，我已经插入了返回的 RGB直接进入 self.panel 本身并且它可以工作，那么为什么当我在此方法中使用它时它不起作用

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 directly into the self.panel itself and it works, so why doesn't it work when I use it within this method

dlg = wx.ColourDialog().SetChooseFull(1) 行似乎是一个错误 - 不是 SetChooseFull 上 wx.ColourData 的方法>？

我做了一些更改以使其正常工作，并对代码进行了注释以进行说明：

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()

data.SetCustomColor(index, color) 填充对话框中的 N 自定义颜色。我在下面的索引 0 处圈出了一个：

在此处输入图像描述

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:
