README for building of ScintillaEditPy on Qt with PySide
|
|
|
|
This directory is for building a Python encapsulation of Scintilla for use
|
|
with PySide. For C++ libraries see the README in the parent directory.
|
|
|
|
Prerequisites
|
|
|
|
PySide and ScintillaEditPy currently only support Python 2.x.
|
|
|
|
CMake may be used to rebuild PySide and is required on Windows.
|
|
It can be downloaded from
|
|
http://www.cmake.org/cmake/resources/software.html
|
|
|
|
On Windows, PySide only supports Visual C++ 2008. The "Visual Studio 2008
|
|
Command Prompt" should be used to run all build commands.
|
|
Visual C++ 2008 Express Edition can be downloaded from
|
|
http://msdn.microsoft.com/en-us/express/future/bb421473
|
|
|
|
Download and install PySide. Instructions are on the PySide web site
|
|
http://developer.qt.nokia.com/wiki/Category:LanguageBindings::PySide::Downloads
|
|
|
|
For Linux, there may be both PySide library packages and PySide development
|
|
files. Both should be installed as ScintillaEditPy needs the headers and
|
|
libraries from the development package and runs with the normal library package.
|
|
On apt-based systems, the packages are libshiboken-dev, shiboken, libpyside-dev,
|
|
and python-pyside. python-dev is also needed for Python language headers.
|
|
On yum-based systems the packages are shiboken-devel, python-pyside-devel,
|
|
and python-devel.
|
|
The qmake program may not be in the path and can be found with
|
|
"find /usr -name qmake".
|
|
|
|
On Windows, the PySide library packages can be downloaded from
|
|
http://developer.qt.nokia.com/wiki/PySide_Binaries_Windows
|
|
The PySide development files must be built from source using CMake as
|
|
described on the PySide site. This will create a Unix-style set of [bin, include,
|
|
lib, and share] directories in packaging\setuptools\install-py<ver>-qt<qver>.
|
|
There is no standard place for the PySide development files so copy them
|
|
to "\usr", creating it if needed.
|
|
|
|
On OS X, a combined package with PySide libraries and PySide development
|
|
files can be downloaded from
|
|
http://developer.qt.nokia.com/wiki/PySide_Binaries_MacOSX
|
|
This package works best in combination with the Qt libraries for Mac from
|
|
http://qt.nokia.com/downloads/downloads#qt-lib
|
|
|
|
The path should be modified so that a Python 2.x interpreter and Qt's "qmake"
|
|
program can be run by typing "python" or "qmake".
|
|
|
|
Building
|
|
|
|
There are several steps to building and they are encapsulated in the sepbuild.py
|
|
script which is run:
|
|
|
|
python sepbuild.py
|
|
|
|
This script first runs the WidgetGen.py script to fill out the ScintillaEdit.h,
|
|
ScintillaEdit.cpp and ScintillaConstants.py files.
|
|
|
|
A short file "sepbuild.pri" is written out which contains a series of version and
|
|
path properties discovered by sepbuild.py which are used by qmake.
|
|
|
|
Then it runs PySide's "shiboken" program to create C++ code that will act as a
|
|
bridge between Python and the C++ libraries. This code goes into the
|
|
ScintillaEditPy/ScintillaEditPy directory. Several log files are produced which can
|
|
help uncover problems in the bridge if it fails to build.
|
|
|
|
The qmake program is run to produce make files from ScintillaEditPy.pro.
|
|
|
|
The system make program is then run to build the library. The library is located in
|
|
the scintilla/bin directory as ScintillaEditPy.so for Unix systems and
|
|
ScintillaEditPy.pyd for Windows.
|
|
|
|
A demonstration program can be run:
|
|
|
|
python testsepq.py
|
|
|
|
The individual steps in the script can be run manually if wanted although the
|
|
shiboken program has complex arguments and differs between systems so run
|
|
sepbuild.py and copy the section starting with a line containing "generatorrunner"
|
|
and continuing to "typesystem_ScintillaEdit.xml".
|
|
|
|
On Windows, it is more difficult to set up an environment to debug ScintillaEditPy
|
|
since all the libraries have to be debug or all have to be release. The easy path
|
|
is to always build for release with "nmake release".
|
|
|
|
To remove generated code, run "python sepbuild.py --clean".
