Returns visibility state for the element. This is a READONLY property

visible

bind

Used to add tkinter events to an Element. The tkinter specific data is in the Element's member variable user_bind_event

block_focus

Enable or disable the element from getting focus by using the keyboard. If the block parameter is True, then this element will not be given focus by using the keyboard to go from one element to another. You CAN click on the element and utilize it.

    expand_y = False,
    expand_row = True
)

expand_y	bool	False	If True Element will expand in the Vertical directions

get

Returns the current (right now) value of the Combo. DO NOT USE THIS AS THE NORMAL WAY OF READING A COMBO! You should be using values from your call to window.read instead. Know what you're doing if you use it.

get()

RETURN	(int, int)		width and height of the element

grab_anywhere_exclude

grab_anywhere_exclude()

grab_anywhere_include

Includes this element in the grab_anywhere feature This will allow you to make a Multline element drag a window for example

Unhides (makes visible again) the row container that the Element is located on. Note that it will re-appear at the bottom of the window / container, most likely.

unhide_row()

update

Changes some of the settings for the Combo Element. Must call Window.Read or Window.Finalize prior. Note that the state can be in 3 states only.... enabled, disabled, readonly even though more combinations are available. The easy way to remember is that if you change the readonly parameter then you are enabling the element.

Changes will not be visible in your window until you call window.read or window.refresh.

If you change visibility, your element may MOVE. If you want it to remain stationary, use the "layout helper" function "pin" to ensure your element is "pinned" to that location in your layout so that it returns there when made visible.

    value = None,
    values = None,
    set_to_index = None,
