Is it possible to have Windows platform plugin with and without DirectWrite in the same build? What I want is a build that produces both the default non-DW version of qwindows.dll and a DW enabled version named, say, qwindows_dw.dll. Our installer will then handle the installation of the correct one according to user’s Windows version.
The first part of the question is: Is Windows platform plugin the only part of Qt that is required for DirectWrite support?
The second question is then how do I change the build to produce both versions of the DLL? My current plan is:
1. Duplicate the whole platforms/windows directory and name it platforms/windows_dw.
2. Change the target to qwindows_dw in platform/windows_dw/windows.pro.
3. Add directwrite to QT_CONFIG in platform/windows_dw/windows.pro.
4. Add windows_dw to SUBDIRS in platforms.pro
Also. Is there a way to control which platform plugin DLL to load at runtime?
Thanks.
