data into native dirs and cleaning up the code. The native part of wxPrintData is now created via the wxPrintFactory. I moved the code for PostScript to /src/generic/prntdlgg. and for MSW to its the respective dir. I only made wxMac compile, but it already has a native print data class, which should be easy to merge. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@29947 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
