- EXPERIMENTAL SWT CODE FOR JFREECHART
- ------------------------------------
- 07 November 2006
- SWT is the Java Standard Widget Toolkit [1], an open source (released under the
- Eclipse Public License) and portable library to create user interfaces. The
- SWT interfaces will use native widget on any operating system it supports.
- This code provide support for using the JFreeChart library directly into
- SWT Composites. Note that there is the alternative to use the SWT_AWT class
- but it will run only with SUN JRE and Java 1.5 (and it is not native, so
- potentially much slower).
- To compile this code, you will need to link it against the swt.jar of the
- target os. Indeed while the API is totally cross platform, the implementation
- is platform dependent since it calls on native widget if available (much
- faster) and only rely on a Java implementation if it is not. An ant script:
- build-swt.xml is provided to help you build the code. This file contains two
- compile targets to build the following jar:
- * swtgraphics2d.jar - The generic classes not JFreeChart specific.
- * jfreechart-1.0.x-swt.jar - The specific JFreeChart SWT classes.
- To get a successful build id pretty straightforward, download the SWT library
- from eclipse.org [1]. Unpack the archive in the JFreeChart tree as libswt.
- If you need to build for multiple OS, put all the SWT in there. For instance
- (with SWT version 3.2):
- libswt
- |
- `--swt-linux-gtk-x86
- | |
- | `--swt.jar
- | `--libswt-gtk-3232.so
- | `-- etc...
- `--swt-win32-win32-x86
- |
- `--swt.jar
- `--swt-win32-3232.dll
- Then you need to edit the build-swt.xml script and change line 14 to what is
- needed. Of course all of the paths are relative. You can change it to whatever
- you like provided the path in the xml file is correct. Then just run:
- ant -buildfile build-swt.xml
