  I have a tkinter app that has 2 frames. The frame on the left has a bunch of buttons and the frame on the right has a text widget. I use the create_buttons function below to make the buttons. Is there a way to have the button stay sunken when clicked. Then when I click the next button that one stays sunken? I want to be able to see the last button clicked.
  def create_buttons(self): ''' Loop that creates a button for each file in lterrors.txt. The buttons uses the client/server name as its title text and a custom action that opens the appropriate file in the text widget. ''' try: with open(App.logfile, 'r') as f: lines = f.readlines() except IOError: message = 'Cannot find %s.' % (App.logfile) showerror(title='Sorry', message=message) labels = [] for i, line in enumerate(lines): filename = line.strip() filename = filename.replace('C:\LTShare', 'L:') host = os.path.dirname(filename) company = os.path.dirname(host) company = os.path.basename(company) host = os.path.split(host)[-1] host = host.split('-')[0] text = company + '-' + host labels.append((text, filename)) labels.sort() for i, data in enumerate(labels): text, filename = data button = Button(self.frame1, text=text, command=lambda filename=filename: self.button_command(filename)) button.grid(row=i, column=0, sticky='EW')
