From: rambetter Date: Wed, 15 Dec 2010 09:52:26 +0000 (+0000) Subject: Progressing on bringing Radiant 1.6.x to a workable state on Windows. X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=7a5d8a111c3725605cfc92ae6e79dd0c7a45e232;p=xonotic%2Fnetradiant.git Progressing on bringing Radiant 1.6.x to a workable state on Windows. This commit: 1. Reverts to using GtkR-deps-1.6-3.zip (instead of GtkR-deps-1.6-4.zip). Some font-related DLLs are therefore no longer used with this patch. 2. Because of the above #1, now using the really old OpenGL font rendering code on Windows systems. This is controlled via "#ifdef _WIN32" blocks. Linux still uses the new and improved OpenGL font rendering. Note that this old font rendering that Windows now uses (err, has used in the past too) makes use of gdk_gl_font_use_pango_font(), which is really old and crufty. So, with this commit Radiant is fully working (modulo bugs) on Linux and Windows, and OpenGL fonts work too. I WOULD NOT SUGGEST MERGING THIS CHANGE INTO TRUNK. THE CORRECT APPROACH IS TO INSTEAD FIX THE DLL LIBRARY DEPENDENCIES IN TRUNK. I AM ONLY COMMITTING THIS SO THAT I CAN CONTINUE FIXING BUGS IN RADIANT IN THE MEANTIME. There are still a zillion bugs on Windows. For example, I can't even save a .map file at this point. That is my next task, to fix saving of .map files. git-svn-id: https://zerowing.idsoftware.com/svn/radiant/GtkRadiant/branches/Rambetter-temp-fixes@350 8a3a26a2-13c4-0310-b231-cf6edde360e5 --- diff --git a/config.py b/config.py index e91e9f1f..e0f20a01 100644 --- a/config.py +++ b/config.py @@ -273,7 +273,7 @@ class Config: self.FetchGamePaks( self.install_directory ) # NOTE: unrelated to self.setup_platforms - grab support files and binaries and install them if ( self.platform == 'Windows' ): - depsfile = 'GtkR-deps-1.6-4.zip' + depsfile = 'GtkR-deps-1.6-3.zip' if ( not os.path.exists( depsfile ) ): cmd = [ 'wget', '-N', 'http://zerowing.idsoftware.com/files/radiant/developer/1.6.1/%s' % depsfile ] print( repr( cmd ) ) @@ -310,9 +310,9 @@ class Config: 'gtk2/lib/libgdkglext-win32-1.0-0.dll', 'gtk2/lib/iconv.dll', 'gtk2/zlib1.dll', - 'freetype-dev_2.4.2-1_win32/bin/freetype6.dll', - 'fontconfig-dev_2.8.0-2_win32/bin/libfontconfig-1.dll', - 'expat_2.0.1-1_win32/bin/libexpat-1.dll', +# 'freetype-dev_2.4.2-1_win32/bin/freetype6.dll', +# 'fontconfig-dev_2.8.0-2_win32/bin/libfontconfig-1.dll', +# 'expat_2.0.1-1_win32/bin/libexpat-1.dll', ]: cmd = [ 'cp', '-v', os.path.join( srcdir, f ), 'install' ] print( repr( cmd ) ) @@ -320,9 +320,9 @@ class Config: for d in [ 'gtk2/etc', 'gtk2/share', - 'fontconfig-dev_2.8.0-2_win32/etc', - 'fontconfig-dev_2.8.0-2_win32/share', - 'freetype-dev_2.4.2-1_win32/share', +# 'fontconfig-dev_2.8.0-2_win32/etc', +# 'fontconfig-dev_2.8.0-2_win32/share', +# 'freetype-dev_2.4.2-1_win32/share', ]: cmd = [ 'cp', '-r', '-v', os.path.join( srcdir, d ), 'install' ] print( repr( cmd ) ) diff --git a/radiant/glwidget.cpp b/radiant/glwidget.cpp index 7a408f9e..57699b37 100644 --- a/radiant/glwidget.cpp +++ b/radiant/glwidget.cpp @@ -33,7 +33,11 @@ SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. #include "stdafx.h" #include + +#ifndef _WIN32 #include +#endif + #include "glwidget.h" #include "qgl.h" @@ -208,6 +212,15 @@ gboolean WINAPI gtk_glwidget_make_current (GtkWidget *widget) } +#ifdef _WIN32 + +GLuint font_list_base; +static gchar font_string[] = "courier 8"; +static gint font_height; +static int font_created = 0; + +#else + // Think about rewriting this font stuff to use OpenGL display lists and glBitmap(). // Bit maps together with display lists may offer a performance increase, but // they would not allow antialiased fonts. @@ -219,31 +232,88 @@ static int y_offset_bitmap_render_pango_units = -1; static PangoContext *ft2_context = NULL; static int _debug_font_created = 0; +#endif + // Units are pixels.
