Huge GtkFB patch with lots of small bugfixes and initial selections implementation. 2000-11-23 Alexander Larsson <alexl@redhat.com> * gdk/linux-fb/gdkselection-fb.c: Initial selection implementation. * gtk/gtkselection.c: if GDK_WINDOWING_FB defined, include linux-fb/gdkfb.h and look up requestor in gtk_selection_request. * gdk/linux-fb/gdkfb.h, gdk/linux-fb/gdkglobals-fb.c: Added gdk_selection_property atom. * gdk/linux-fb/gdkprivate-fb.h: Export _gdk_selection_window_destroyed. Removed mask_off_x/y from GdkCursorPrivateFB. Removed hbearing, added top, left to PangoFBGlyphInfo. * gdk/linux-fb/gdkwindow-fb.c (_gdk_windowing_window_destroy): Call _gdk_selection_window_destroyed (_gdk_windowing_window_init): Don't call gdk_cursor_new() before the root window has been created. (static_dx_hack, static_dy_hack, compare_draw_rects, gdk_fb_window_move_resize): Remove unnecessary sort of rectangles in region. They are already sorted. Instead just traverse them in reverse if draw_direction < 0. * gdk/linux-fb/gdkinput-ps2.c (send_button_event): Double-clicks must be sent after the normal button_press. (gdk_fb_cursor_unhide): Remove usage of mask_off_x/y. Clean up. * gdk/linux-fb/gdkgeometry-fb.c (gdk_window_scroll): Pass _gdk_fb_screen_gc instead of NULL. * gdk/linux-fb/gdkmain-fb.c (_gdk_windowing_init_check): Initialize gdk_selection_property. (gdk_event_make): Remove unused code. * gdk/linux-fb/gdkcursor-fb.c: Make the pixmap for the cursor the same size as the mask. Also remove the mask_off_x/y fields in GdkCursorPrivateFB and combine _gdk_cursor_new_from_pixmap() and gdk_cursor_new_from_pixmap() Now the whole cursor is visible. * gdk/linux-fb/gdkdrawable-fb2.c (gdk_fb_draw_drawable_3): Fix bug where xdest+height instead of ydest+height was used to calculate if the source and dest overlapped. This fixes the redraw bug when the main window in testgtk was scrolled when partially covered by a tall window. Copy rectangles in region in order depending on draw_direction. Also moved the draw_direction flipping of start_y and end_y into the gc functions, as this might not be what all of them want. (gdk_fb_draw_lines): Support dashed lines. (gdk_fb_draw_glyphs): Clean up glyph placement. Also fix positioning so that the text is positioned correctly (was 1 pixel high). gdk/linux-fb/gdkgc-fb.c: Initialize cap_style to GTK_CAP_BUTT. This fixes a problem where all lines were drawn a pixel to short. Also checked the default of the rest of the values, and they're the same as X now. * gdk/linux-fb/gdkpango-fb.c (pango_fb_font_get_glyph_info): Clean up pixel positioning of the glyphs. Just use bgy->top and bgy->left. Also used PANGO_PIXEL where appropriate and added 0.5 to all divisions to get correct rounding behaviour. * gdk/linux-fb/gdkrender-fb.c (gdk_fb_draw_drawable_generic, gdk_fb_draw_drawable_memmove, gdk_fb_draw_drawable_aa_24): Moved start_y/end_y flip into draw_drawable implementations. Flip also x rendering when draw_direction < 0. Remove unneccesary multiply with draw_direction.

Added ENABLE_SHADOW_FB 2001-01-11 Alexander Larsson <alexl@redhat.com> * acconfig.h: Added ENABLE_SHADOW_FB * configure.in: Added --disable-shadowfb * gdk/linux-fb/gdkcursor-fb.c: Update shadowfb when updating cursor * gdk/linux-fb/gdkdrawable-fb2.c: Added wrappers for shadowfb that calls the normal drawable methods, but calls gdk_shadow_fb_update(bounding box) when GdkWindows are drawed to. Moved gdk_draw_glyphs implementation to _gdk_draw_glyphs which also returns the bounding box. * gdk/linux-fb/gdkfb.h: Added GdkFBAngle type and gdk_fb_set_rotation declaration. * gdk/linux-fb/gdkgeometry-fb.c: Update shadowfb when scrolling window. * gdk/linux-fb/gdkglobals-fb.c: Add _gdk_fb_screen_angle. * gdk/linux-fb/gdkkeyboard-fb.c: Test code for screen rotation. Shift-F2 in the xlate driver rotates the screen. * gdk/linux-fb/gdkmain-fb.c: Handle shadowfb. Add gdk_fb_set_rotation(). Remove CM and RP. * gdk/linux-fb/gdkmouse-fb.c: Use fb_width/height instead of modeinfo.xres/yres. * gdk/linux-fb/gdkprivate-fb.h: Added fb_men, fb_width, fb_height & fb_stride. When using shadow fb these can differ from the framebuffer stuff. Declarations for gdk_shadow_fb_update, gdk_shadow_fb_init, gdk_shadow_fb_stop_updates, gdk_fb_recompute_all, _gdk_fb_screen_angle. Removed CM, RP. * gdk/linux-fb/gdkrender-fb.c: Added code for shadowfb handling and screen rotation using shadowfb. * gdk/linux-fb/gdkwindow-fb.c: Use fb_mem, fb_stride, fb_width, fb_height. Added recompute_rowstride to reset the rowstride of all windows. Added gdk_fb_recompute_all() which recomputes rootwindow size, window abs positions and window rowstrides. Usefull when the rotation has changed.
