The child widgets can be resized by the user, by moving separator lines sashes using the mouse.

Tkinter comboboxes. As you know, I am working with Tkinter as a graphical library for a short time, and my first reference is the book Tkinter GUI Application Development, already reviewd here on manejandodatos.es. But sometimes, things are not as you like, and that’s my problem with combobox (and Listboxes). This book covers all of your Tkinter and Python GUI development problems and solutions. Tkinter GUI Application Development Cookbook starts with an overview of Tkinter classes and at the same time provides recipes for basic topics, such as layout patterns and event handling. In Python 3, tkinter is still available, but the import names changed. In Python 2 the main package is Tkinter and there are additional packages like the toolkit ttk and constants Tkconstants. In Python 3 the naming and organization was improved. Everything is now under the tkinter package. There is tkinter, tkinter.constants, and tk.ttk. The ... Tkinter LabelFrame. The LabelFrame widget is used to draw a border around its child widgets. We can also display the title for the LabelFrame widget. It acts like a container which can be used to group the number of interrelated widgets such as Radiobuttons. This widget is a variant of the Frame widget which has all the features of a frame. VIRTUAL EVENTS The combobox widget generates a <<ComboboxSelected>> virtual event when the user selects an element from the list of values. If the selection action unposts the listbox, this event is delivered after the listbox is unposted.
