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.
