2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data. |
