wxPython - 更改按钮的前景色

在本文中,我们将学习如何更改按钮的前景色或按钮的字体颜色。为此,我们将使用与 wxPython 的 wx.Button 类关联的 SetForegroundColour()函数。

SetForegroundColour()函数只需将 wx.Colour 参数用于前景。

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)
  
        # create parent panel for button        
        self.pnl = wx.Panel(self)
  
        # create button at point (20, 20)
        self.btn = wx.Button(self.pnl, id = 1, label ="Button", pos =(20, 20),
                                            size =(300, 40),  name ="button")
  
        # change foreground colour of button to blue
        self.btn.SetForegroundColour((0, 0, 255, 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()
