wxPython - EnableItem() function in wx.RadioBox

In wxPython, the wx.RadioBox widget is a container for a group of radio buttons. The EnableItem() function of wx.RadioBox is used to enable or disable individual radio buttons in the group.

Here's a brief explanation of the EnableItem() method:

Method Signature:

EnableItem(item, enable=True)

Parameters:

  • item: Index of the radio button within the wx.RadioBox to be enabled or disabled.
  • enable: Boolean value to indicate whether the item should be enabled (True) or disabled (False).

Example:

Suppose you have a wx.RadioBox with 3 radio button choices, and you want to disable the second choice:

import wx class MyFrame(wx.Frame): def __init__(self, *args, **kw): super(MyFrame, self).__init__(*args, **kw) self.panel = wx.Panel(self) # Choices for the RadioBox choices = ['Choice 1', 'Choice 2', 'Choice 3'] self.radioBox = wx.RadioBox(self.panel, label='RadioBox Example', choices=choices, majorDimension=1, style=wx.RA_SPECIFY_COLS) # Disable the second choice self.radioBox.EnableItem(1, False) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.radioBox, 0, wx.ALL, 5) self.panel.SetSizer(sizer) self.Show() if __name__ == '__main__': app = wx.App(False) frame = MyFrame(None, title='EnableItem Example') app.MainLoop()

In the example above, self.radioBox.EnableItem(1, False) disables the second radio button choice (indexed at position 1, since indices are 0-based).

This is useful when certain conditions in your application make some choices invalid or when you want to direct the user's attention to specific options.
