Copy qprintengine_mac_p.h, qprintengine_mac.mm, qpaintengine_mac_p.h,
and qpaintengine_mac.cpp (as qpaintengine_mac.mm) from src/gui/painting/
in the 4.8 branch of http://git.gitorious.org/qt/qt.git at commit
e6bd33d4aef0e4538d7918e7ab130624c911b553.
The following changes are necessary to port these files to the Qt 5 API:
- The copyright notice on these files has been updated to match the
header.LGPL template.
- Fix #includes for qprintengine_mac* and qpaintengine_mac*, as some
headers have moved in Qt 5.
- Remove extern forward declarations for functions that no longer exist.
- Remove friend declarations for classes/functions that are not part of
the Cocoa platform plugin.
- Remove QT_MAC_USE_COCOA blocks. Qt is always using Cocoa now, there
is no need to keep the non-Cocoa code paths anymore. The
QMacPrintEngine::shouldSuppressStatus() method was also removed,
since it is no longer used.
- Do not use Qt::UniteClip, it was removed in commit
01b72952c3
- Use QCocoaAutoReleasePool in qprintengine_mac.mm
- Use QPlatformPrintSupport::convert*() functions in QMacPrintEngine,
since we cannot use non-exported functions from QtPrintSupport in the
Cocoa plugin.
- Use qt_mac_image_to_cg_image() to convert QPixmap to CGImageRef. First
convert QPixmap to QImage (cheap, since the Cocoa platform plugin
uses QRasterPlatformPixmap), and then convert the QImage to CFImageRef
using the existing helper function.
- Copy qt_mac_cg_context() to the Cocoa platform plugin from
qmacstyle_mac.mm, adding a note at each location about the
duplication.
- Add qt_mac_QRegionToHIMutableShape() helper. Adapt the Qt 4.x code for
QRegion::toHIMutableShape(), and use this in QCoreGraphicsPaintEngine.
- Add qt_mac_drawCGImage() and qt_mac_get_scalefactor() helper. These
functions are copied directly from the 4.8 branch of
http://git.gitorious.org/qt/qt.git at the same revision shown above.
- Add qt_mac_create_imagemask() helper in qpaintengine_mac.cpp. This
helper is based on the function with the same name from the 4.8
branch of http://git.gitorious.org/qt/qt.git at the same revision
shown above. The correctness of the implementation has not yet been
verified.
Since these files use the QPrinter API from QtPrintSupport, the Cocoa
plugin now needs to link to that library as well.
