wxPython – wx.Button 中的 SetBitmapPosition()函数

在本文中，我们将学习与 wxPython 的 wx.Button 类关联的 SetBitmapPosition()函数。 SetBitmapPosition()函数用于设置要设置的位图方向。

方向：
1. wx.LEFT
2. wx.RIGHT
3. wx.BOTTOM
3.wx.TOP

Syntax: wx.Button.SetBitmapPosition(self, dir)

Parameters:

Parameter	Input Type	Description
dir	Direction	Direction in which the bitmap should be positioned, one of wx.LEFT, wx.RIGHT, wx.TOP or wx.BOTTOM.

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 bitmap
        bmp = wx.Bitmap('pointer.png')
  
        # create button at point (20, 20)
        self.st = wx.Button(self.pnl, id = 1, label ="Button", pos =(20, 20),
                                          size =(300, 40),  name ="button")
  
        # set bitmap for button
        self.st.SetBitmap(bmp)
  
        # change position of bitmap to right
        self.st.SetBitmapPosition(wx.RIGHT)
  
        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()
