foo = PhotoImage # foo may clear by garbage collection, can assign to class to prevent button.image = foo 

The following are some of the most useful methods: - winfo_class: a class identifying the type of widget, e.g. TButton for a themed button - winfo_children: a list of widgets that are the direct children of a widget in the hierarchy - winfo_parent: parent of the widget in the hierarchy - winfo_toplevel: the toplevel window containing this widget - winfo_width, winfo_height: current width and height of the widget; not accurate until appears onscreen - winfo_reqwidth, winfo_reqheight: the width and height the widget requests of the geometry manager (more on this shortly) - winfo_x, winfo_y: the position of the top-left corner of the widget relative to its parent - winfo_rootx, winfo_rooty: the position of the top-left corner of the widget relative to the entire screen the position of the top-left corner of the widget relative to its parent - winfo_rootx, winfo_rooty: the position of the top-left corner of the widget relative to the entire screen - winfo_vieweable: whether the widget is displayed or hidden (all its ancestors in the hierarchy must be viewable for it to be viewable) 

screen_width = win.winfo_screenwidth() screen_height = win.winfo_screenheight() #Print the screen size print("Screen width:", screen_width) print("Screen height:", screen_height)

bind & bind_all bind_all: a certain event calls a handler no matter what widget has the focus or is under the mouse
