Question

I have a Tix.ComboBox with an editable text field. How do I force the variable holding the value for the text to update?

Let me give a more concrete explanation. I have a combo box and a button. When I click the button, it pops up a message box with the value of the combo box. Let’s say the combo box text field currently has the value ‘thing1’. If I type ‘new’ into the box and then click on the button with my mouse, it will pops up the message ‘thing1’. If I type ‘new’ in the box and then tab focus away from the combo box and then click the button the pop up message says ‘new’.

Ho do I force the combo box to update it’s value to new without requiring that I tab away from the combo box?

I have included sample code.

import Tix import tkMessageBox  class App(object):     def __init__(self, window):         window.winfo_toplevel().wm_title('test')         self.window = window          self.combo = Tix.ComboBox(window)         self.combo.insert(Tix.END, 'thing1')         self.combo.insert(Tix.END, 'thing2')         self.combo.entry['state'] = 'normal'         self.combo['editable'] = True         self.combo.pack()          button = Tix.Button(window)         button['text'] = 'Go'         button['command'] = self.go         button.pack()      def go(self):         tkMessageBox.showinfo('info', self.combo['value'])   if __name__ == '__main__':     root = Tix.Tk()     App(root)     root.mainloop()

woo! solved it on my own.

Use

self.combo['selection'] 

instead of

self.combo['value']
