wxPython - 使用按钮更改标签

在本文中，我们将学习如何使按钮与框架交互。在本文中，我们将更改按下按钮上的文本标签。因此，让我们从步骤开始。

Step 1: Create a static text on the frame.
Step 2: Add button to the frame.
Step 3: Create event function for the button.
Step 4: Add code to change text label in this function.

代码 ：

# import wxPython
import wx
  
class Example(wx.Frame):
    def __init__(self, *args, **kw):
        super(Example, self).__init__(*args, **kw)
  
        # function to get response after click
        def onButton(event):
            print("Button")
            st.SetLabel("GeeksforGeeks")
  
        # static text
        st = wx.StaticText(self, label ="Welcome to ")
  
        # create button
        button = wx.Button(self, wx.ID_ANY, 'Test', (10, 40))
  
        # bind onButton() function with button
        button.Bind(wx.EVT_BUTTON, onButton)
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
if __name__ == '__main__':
    main()

输出：
1.点击前：

2.点击后
