2002-11-15 Tor Lillqvist <firstname.lastname@example.org> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.fda3e296
