Multiline

Multiline documentation

Multiline Element - Display and/or read multiple lines of text. This is both an input and output element. Other PySimpleGUI ports have a separate MultilineInput and MultilineOutput elements. May want to split this one up in the future too.

block_focus(
    block = True
)

Parameter Descriptions

Name Type Default Description

get()

Parameter Descriptions

Name Type Default Description
RETURN str current contents of the Multiline Element (used as an input type of Multiline

Return the size of an element in Pixels. Care must be taken as some elements use characters to specify their size but will return pixels when calling this get_size method.

get_size()

Parameter Descriptions

Name Type Default Description
RETURN (int, int) width and height of the element

grab_anywhere_exclude

Excludes this element from being used by the grab_anywhere feature Handy for elements like a Graph element when dragging is enabled. You want the Graph element to get the drag events instead of the window dragging.

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

grab_anywhere_include()

hide_row

Hide the entire row an Element is located on. Use this if you must have all space removed when you are hiding an element, including the row container

hide_row()

print

Print like Python normally prints except route the output to a multiline element and also add colors if desired

colors -(str, str) or str. A combined text/background color definition in a single parameter

There are also "aliases" for text_color, background_color and colors (t, b, c) t - An alias for color of the text (makes for shorter calls) b - An alias for the background_color parameter c - (str, str) - "shorthand" way of specifying color. (foreground, backgrouned) c - str - can also be a string of the format "foreground on background" ("white on red")

With the aliases it's possible to write the same print but in more compact ways: cprint('This will print white text on red background', c=('white', 'red')) cprint('This will print white text on red background', c='white on red') cprint('This will print white text on red background', text_color='white', background_color='red') cprint('This will print white text on red background', t='white', b='red')

font (str or (str, int[, str]) or None) None specifies the font family, size, etc. Tuple or Single string format 'name size styles'. Styles: italic * roman bold normal underline overstrike for the args being printed

Changes some of the settings for the Multiline Element. Must call Window.read or set finalize=True when creating window.

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.
