The PLIB3.GUI package contains a simple GUI application framework with two main features:
- It lets the same high-level code work with a number of different underlying GUI toolkits. Currently supported: Qt 4, PySide, KDE 4, and wxPython. (The original reason for writing this sub-package was that wxWidgets doesn't use Qt and I like the Qt/KDE widgets better, but Qt was not available for Windows and I wanted code that would run cross-platform.) Note that the KDE 4 and wxPython toolkits are untested at this time.
- It allows you to express the layout of your GUI in terms of Python lists and dicts, enabling a much more declarative and easy to read (and maintain) coding style.
Other than selecting the toolkit (which may not be necessary: the main module of the sub-package can 'auto-detect' which toolkit to use--the plib-setup-gui post-install script does most of the work to enable this--so you only need to override if you don't like the default), you should not have to worry about any toolkit internal details; the goal of this sub-package is to make them all look the same to your code.
Note: PLIB3.GUI works with Python 3. If you are using Python 2.7, see the PLIB.GUI package, available at https://bitbucket.org/pdonis/plib-gui.
The setup.py script for PLIB3.GUI uses the setuputils helper module, which helps to automate away much of the boilerplate in Python setup scripts. This module is available as a separate release at https://github.com/pdonis/setuputils3.
To install PLIB3.GUI, you can simply run:
$ python setup.py install
at a shell prompt from the directory into which you unzipped the source tarball (the same directory that this README file is in). This will install PLIB3 and then run each of the post-install scripts in the scripts directory.
PLIB3.GUI comes with example programs that illustrate key features of the package. After installation, these can be found in the $PREFIX/share/plib/examples directory. If you have a POSIX system (Linux or Mac OSX), the plib-setup-examples post-install script will install symlinks to the example programs in the $PREFIX/bin directory.
The Zen of PLIB3
There is no single unifying purpose or theme to PLIB3, but like Python itself, it does have a 'Zen' of sorts:
- Express everything possible in terms of built-in Python data structures.
- Once you've expressed it that way, what the code is going to do with it should be obvious.
- Avoid boilerplate code, and boilerplate data. Every piece of data your program needs should have one and only one source.
