I’ll learn more about the difference between quit() and destroy() and give a little explanation later on. In this way, the “quit” problem is solved. (in namespace inscope "::" script line 1) Syntax: widget.winfoexists () Return value: Returns True if widget exists, False otherwise. (procedure "ttk::entry::AutoScroll" line 3) This method is used to check if the specified widget exists or not i.e if the widget is destroyed or not. Sometimes an “can’t invoke “winfo” command:” error appears as the following: can't invoke "winfo" command: application has been destroyed
#TKINTER WINFO EXISTS CODE#
In executing this fragment of code by command “python filename“, every time when the exit button is clicked, the process doesn’t stop correctly. I am working on a project requiring to embed a matplotlib-created-chart into a Tkinter GUI window. lift() method to only raise a window above another one.I’ve encountered an issue recently. lower() method, similarly this can also be done with the. You will notice that it lowers even below other applications, to only lower below a certain window you can pass it to the. The fullscreen mode is updated to the toggled state in this. F11 is bound to the function toggleFullScreen.
#TKINTER WINFO EXISTS WINDOWS#
The attributes in Windows are, -fullscreen specifies whether the window is full-screen mode or not. tk.Tk.attributes sets platform specific attributes.
#TKINTER WINFO EXISTS FULL#
Label = tk.Label(extra, text="extra window") Windows root.attributes ('-fullscreen', True) to Create Full Screen Mode in Tkinter. lift() method, except lowering the window in the stack: import tkinter as tk #import Tkinter as tk #change to commented for python2 lower() method that works the same way as the. winfo_exists() to check if it exists before trying to lift the window instead of wrapping it in a try:except.
This way the function show_dialog will show the dialog window whether it exists or not, also note that you can call. winfocolormapfull, winfocontaining, winfodepth, winfoexists, winfofpixels, winfogeometry, winfoheight, winfoid. #but sometimes extra code will be wanted the first time it is created #this can be refactored to only have one call to create_dialog() However if that window is destroyed trying to lift it will raise an error. """lifts the dialog_window if it exists or creates a new one otherwise""" Label1 = tk.Label(dialog_window,text="this is the dialog window")ĭialog_window.lift() #ensure it appears above all others, probably will do this anyway If you are unsure if it already exists or not use show_dialog()"""
** do not call if dialog_window is already open, this willĬreate a duplicate without handling the other Often when we are trying to put a particular window in front of the user but it was closed a good alternative is to recreate that window: import tkinter as tk #import Tkinter as tk #change to commented for python2 _tkinter.TclError: bad window path name ".4385637096" Self.tk.call('raise', self._w, aboveThis) However if that window is destroyed trying to lift it will raise an error like this: Exception in Tkinter callbackįile "/./tkinter/_init_.py", line 1549, in _call_įile "/./tkinter/_init_.py", line 785, in tkraise Label = tk.Label(window,text="window ".format(i), command=window.lift) lift() method on that window (either Toplevel or Tk) import tkinter as tk #import Tkinter as tk #change to commented for python2 The most basic case to lift a particular window above the others, just call the.
