pythondialog

3.5.3 verified Fri May 01 auth: no python

A Python interface to the UNIX dialog utility (and mostly-compatible programs like whiptail). Current version 3.5.3, requires Python >=3. Stable, infrequent releases.

pip install pythondialog

Common errors

error ModuleNotFoundError: No module named 'dialog' ↓

cause pythondialog is not installed or the import path is wrong.

fix

Run pip install pythondialog and use from dialog import Dialog.

error dialog: command not found ↓

cause The underlying dialog utility is missing.

fix

Install dialog: sudo apt install dialog (Linux) or brew install dialog (macOS).

Warnings

gotcha The `dialog` backend must be installed separately (e.g., `apt install dialog`). pythondialog wraps the system utility. ↓

fix Install dialog from your package manager (e.g., `sudo apt install dialog` or `brew install dialog`).

breaking The `setup.py` no longer supports Python 2. Python 2 support was dropped in version 3.5.0. ↓

fix Use Python 3.4+ (preferably 3.6+).

deprecated The `common_args_screen_size` parameter (used to force size calculation) is deprecated; use `autowidgetsize` instead. ↓

fix Replace `common_args_screen_size=True` with `autowidgetsize=True` in Dialog constructor.

Imports

Dialog
wrong
```
import dialog
```
correct
```
from dialog import Dialog
```
Importing dialog imports the module, but `Dialog` is the class.

Quickstart

Initialize Dialog and show a message box.

from dialog import Dialog
d = Dialog(dialog="dialog")
d.msgbox("Hello, world!")
