Entrada y salida de y hacia la pantalla

La salida estándar de Python no esta disponible cuando se ejecutan macros Python desde el menúHerramientas – Macros - Ejecutar Macro. Presentar la salida de una macro requiere la consola interactiva de Python. Funciones como input(), print(), repr() y str() están disponibles desde la consola de Python.

La extensión Organizador de macros Python alternativo (APSO por sus siglas en ingles) ofrece la función msgbox() desde su modulo apso_utils.


LibreOffice Basic proposes InputBox(), Msgbox() and Print() screen I/O functions. Python alternatives exist relying either on LibreOffice API Abstract Windowing Toolkit, either on Python to Basic function calls. The latter proposes a syntax that is intentionally close to that of Basic, and uses a Python module next to a Basic module. The API Scripting Framework is used to perform Basic, BeanShell, JavaScript and Python inter-languages function calls.

Sintaxis de Python:

MsgBox(txt, buttons=0, title=None)

InputBox(txt, title=None, default=None)

Print(txt)

Ejemplos:

>>> import screen_io as ui

>>> reply = ui.InputBox('Please enter a phrase', title='Dear user', defaultValue="here..")

>>> rc = ui.MsgBox(reply, title="Confirmation of phrase")

>>> age = ui.InputBox('How old are you?', title="Hi")

>>> ui.Print(age)
