pythondialog is a Python wrapper for the dialog utility originally written by Savio Lam, and later rewritten by Thomas E. Dickey. Its purpose is to provide an easy to use, pythonic and comprehensive Python interface to dialog. This allows one to make simple text-mode user interfaces on Unix-like systems (including Linux).
The following example is written for pythondialog 3, because it
d.OK (attribute of the
Dialog class accessed
through the d
Dialog instance), which is new in
pythondialog 3. If you want it to work with pythondialog 2,
simply replace all occurrences of
Note: the old syntax (
d.DIALOG_OK) still works in
pythondialog 3, but is deprecated.
#! /usr/bin/env python3 import locale from dialog import Dialog # This is almost always a good thing to do at the beginning of your programs. locale.setlocale(locale.LC_ALL, '') # You may want to use 'autowidgetsize=True' here (requires pythondialog >= 3.1) d = Dialog(dialog="dialog") # Dialog.set_background_title() requires pythondialog 2.13 or later d.set_background_title("My little program") # For older versions, you can use: # d.add_persistent_args(["--backtitle", "My little program"]) # In pythondialog 3.x, you can compare the return code to d.OK, Dialog.OK or # "ok" (same object). In pythondialog 2.x, you have to use d.DIALOG_OK, which # is deprecated since version 3.0.0. if d.yesno("Are you REALLY sure you want to see this?") == d.OK: d.msgbox("You have been warned...") # We could put non-empty items here (not only the tag for each entry) code, tags = d.checklist("What sandwich toppings do you like?", choices=[("Catsup", "", False), ("Mustard", "", False), ("Pesto", "", False), ("Mayonnaise", "", True), ("Horse radish","", True), ("Sun-dried tomatoes", "", True)], title="Do you prefer ham or spam?", backtitle="And now, for something " "completely different...") if code == d.OK: # 'tags' now contains a list of the toppings chosen by the user pass else: code, tag = d.menu("OK, then you have two options:", choices=[("(1)", "Leave this fascinating example"), ("(2)", "Leave this fascinating example")]) if code == d.OK: # 'tag' is now either "(1)" or "(2)" pass
For more examples, see simple_example.py and demo.py in a release tarball (simple_example.py is only included in versions 2.14.0 and later).
The main changes between the various pythondialog releases are described on the news page.
- For the reference implementation (which is written for Python 3), go to the PyPI page for pythondialog.
- For the Python 2 backport, recent versions are available on the PyPI page for the Python 2 backport of pythondialog.
Debian users: there is now an up-to-date package for Python 3 in unstable (actually, the package from experimental will be even more up-to-date as long as jessie is frozen). The binary package is named python3-dialog, therefore it can be installed with:
apt-get install python3-dialog
Other Linux distributions such as Gentoo may also propose pythondialog from their software repositories.
