wxPython - 更改按钮的背景颜色

在本文中，我们将学习如何更改框架中按钮的背景颜色。我们使用 SetBackgroundColour()函数将按钮的背景颜色设置为不同的颜色。
它需要一个 wx.Colour 类对象作为参数。

Syntax: wx.Button.SetBackgroundColour(self, colour)

Parameters:

Parameter	Input Type	Description
colour	wx.Colour	Colour for the background.

代码示例：

import wx
  
  
class Example(wx.Frame):
  
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
        self.InitUI()
  
    def InitUI(self):
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
        self.pnl = wx.Panel(self)
        font = wx.Font(10, family = wx.FONTFAMILY_MODERN, style = 0, weight = 90,
                        underline = False, faceName ="", encoding = wx.FONTENCODING_DEFAULT)
  
        self.btn = wx.Button(self.pnl, id = 1, label ="Click", pos =(20, 20),
                                size = wx.DefaultSize, name ="statictext")
        self.btn.SetFont(font)
          
        # SET BACKGROUND COLOUR
        self.btn.SetBackgroundColour((255, 230, 200, 255))
        self.SetSize((350, 250))
        self.SetTitle('wx.Button')
        self.Centre()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
