This method is used to check if the specified widget exists or not i.e if the widget is destroyed or not. Label = ttk.Label(frame, text="Message:")īutton = ttk.Button(frame, text="Comment") w.after(delayms, callbackNone, args) Requests Tkinterto call function callbackwith arguments argsafter a delay of at least delaymsmilliseconds. descriptions, wcan be any widget of any type. (This uses python3 as that is what I have). Universal widget methods The methods are defined below on all widgets. EDITĪ modified example follows to show how to use Toplevel and wm_transient for this purpose, along with a grab to make a modal dialog and placing the new dialog on top of the parent widget. while executing winfo exists pb (procedure ttk::progressbar::Autoincrement line 4). It is also good to set the dialog toplevel as transient for its parent ( dlg.wm_transient(root)) so that the window manager only shows a taskbar icon for the application root and not for every dialog it creates. ![]() This way the window manager will see the proper hierarchy of windows. ![]() It returns a Boolean value where True (1) specifies that the widget exists in the application, and False (0) specifies that the widget doesn't exist in the application. The method can be invoked with the particular widget we want to check. A toplevel has an owner which can be the Tk root window or other application window. If we want to check if a widget exists or not, then we can use the winfoexists () method. Instead we have Toplevel for new toplevel windows (ie dialogs). However, you should not be calling Tk() again in the message function. You can check for the existence of a window using the winfo_exists() method of the widget object. The tkinter.ttk module provides access to the Tk themed widget set, introduced in Tk 8.5.
