wxPython – Dynamically enable and disable tools in toolbar using button

0 0 1 minute read

In this article we are going to learn how can we enable and disable dynamically using a single button. We will create a button and a toolbar with a single tool. We will use a normal button like a toggle button.

Steps :

1. Create a toolbar in a frame.
2. Add a tool with a certain id.
3. Create button in the window.
4. Declare a global count variable and initialize it to zero.
5. Increment when button is clicked.
6. If count is even then enable tool else disable tool.

Code Example:

import wx 
  
  
class Example(wx.Frame): 
  
    def __init__(self, *args, **kwargs): 
        super(Example, self).__init__(*args, **kwargs) 
  
        self.InitUI() 
  
    def InitUI(self): 
        pnl = wx.Panel(self) 
        self.toolbar = self.CreateToolBar() 
        qtool = self.toolbar.AddTool(12, 'Quit',  
                     wx.Bitmap('/Desktop/wxPython/signs.png')) 
        self.toolbar.Realize() 
  
        self.Bind(wx.EVT_TOOL, self.OnQuit, qtool) 
  
        self.SetSize((350, 250)) 
        self.SetTitle('Simple toolbar') 
        self.Centre() 
        self.btn = wx.Button(pnl, label ='Close', pos =(20, 20)) 
  
        self.btn.Bind(wx.EVT_BUTTON, self.Onclick) 
  
        self.SetSize((350, 250)) 
        self.SetTitle('wx.Button') 
        self.Centre() 
  
  
    def OnQuit(self, e): 
        self.Close() 
  
    def Onclick(self, e): 
        # disable tool using EnableTool 
        self.toolbar.EnableTool(12, False) 
  
  
def main(): 
  
    app = wx.App() 
    ex = Example(None) 
    ex.Show() 
    app.MainLoop() 
  
  
if __name__ == '__main__': 
    main()
