I have just finished implementing native gradients for the remaining qt devices (revision 10675).
The whole exercise was my first really positive experience with C++. For example, I feel I am finally beginning to understand OOP (especially inheritance) after years of avoiding thinking about it. Of course, I am still just a C++ newbie so I would appreciate review of my recent commits to qt.h, plqt.cpp, and qt.cpp to see if there are slicker ways to get the job done or obvious memory leak issues that need to be addressed. However, native gradients do seem to be working now for qt raster devices, svgqt, epsqt/pdfqt, and qtwidget. I don't have a test for extqt, but QtExtWidget (the class associated with extqt) inherits from QtPLWidget (the class associated with the tested qtwidget case) so I believe it should be fine. valgrind checks on all classes of qt devices show no memory management issues. valgrind does report memory leak issues (one of my motivations for requesting review of my commits), but those memory leaks might be associated with the Qt-4.6.0 libraries rather than our own code since even with "valgrind --leak-check=full --num-callers=40" it is difficult to pin down the sources of the memory leaks. Next up; dive back into C again, and implement native gradients for the cairo devices. Alan __________________________ Alan W.
