Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Chris Mumby (chrismumby) Assigned to: Nobody/Anonymous (nobody) Summary: Blank window when using wxWidgets driver in Windows Initial Comment: After building project files for VC++2005 Express from the latest svn checkout and compiling the libs and then the examples, running any of the demo's with the wxWidgets driver selected always resulted in a blank screen (client area). That is, there was a window and there was also a white cursor. After managing to get VC++ to step through the library code I saw that the wxDc object never got created 9remained null) and that the flags in wxPlDev for freetype, antiliasing were uninitialised and thus some non-zero number which when used in an if statement to test the flag for true or false always resulted in true. So i zeroed these in the c'tor of wxPlDev and recompiled, and the examples now work, I can see the graphs. This is my first bug report, and have done a diff (from TortoiseSVN) which although I have never used assume it is easy to use this file with a program to patch the file. the file modified is wxwidgets.cpp (4 lines) in the folder drivers. Only tested on winxp SP2 and wxWidgets cvs head, although i had the same problem when i last tried with 2.8. I hope this is the right place for the patch.
