2001-06-28 Havoc Pennington <hp@pobox.com> * gdk/x11/gdkimage-x11.c (_gdk_x11_get_image): Clip the retrieved image data to the screen, using a server grab to avoid race conditions. * gtk/gtkitemfactory.c (gtk_item_factory_create_item): remove check for NULL return from gtk_image_new_from_stock(), it never returns NULL. (gtk_item_factory_create_item): fix bug where we parsed the stock ID as an inline pixbuf * gtk/gtktext.c (gtk_text_key_press): numeric keypad support * gtk/gtkspinbutton.c (gtk_spin_button_key_press): numeric keypad support (should be using binding set here) * gtk/gtkoptionmenu.c (gtk_option_menu_key_press): numeric keypad support (should be using binding set here) * gtk/gtkmenushell.c (gtk_menu_shell_class_init): numeric keypad support * gtk/gtkmenu.c (gtk_menu_class_init): numeric keypad support * gtk/gtkmenubar.c (gtk_menu_bar_class_init): numeric keypad * gtk/gtklistitem.c (gtk_list_item_class_init): numeric keypad * gtk/gtkimcontextsimple.c (gtk_im_context_simple_filter_keypress): keypad * gtk/gtkfilesel.c (gtk_file_selection_key_press): keypad * gtk/gtkentry.c (gtk_entry_class_init): numeric keypad fixes * gtk/gtkctree.c (gtk_ctree_class_init): numeric keypad support * gtk/gtkcolorsel.c (palette_activate): keypad support (of course, should be binding-setted) * gtk/gtkwindow.c (gtk_window_class_init): numeric keypad fixes * gtk/gtkclist.c (gtk_clist_class_init): numeric keypad fixes * gtk/gtkcalendar.c: numeric keypad fixes * gtk/gtktextview.c (gtk_text_view_class_init): numeric keypad support * gdk/gdkwindow.c (gdk_window_get_clip_region): fix infinite loop screwup * gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha): clip the render area to the drawable's clip region in advance, so we don't get data from the server that we don't need. * gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha): check return value of gdk_pixbuf_get_from_drawable(), fall back to bilevel alpha if we can't get the pixbuf to composite against. * gdk/gdkdraw.c (gdk_drawable_get_image): set the image colormap * gdk/gdkimage.c (gdk_image_get_colormap): add gdk_image_set_colormap, gdk_image_get_colormap * gdk/gdkpixbuf-drawable.c (rgbconvert): Change all converters to take a region of the image, instead of converting the entire image. * gtk/gtkwidget.h (struct _GtkWidgetClass): add show_help keybinding signal. Add default bindings for it. Add default handler for show_help that shows the tooltip for the widget. * gtk/gtkdialog.c (gtk_dialog_class_init): add binding set and "close" keybinding signal, remove key press handler. * gtk/gtktooltips.c (gtk_tooltips_set_colors): Just remove this, it's not our usual practice to leave a deprecated function around with a runtime warning, plus we don't want it to appear in docs, plus if we make them yellow no one will want to change them anyhow.

/* Types of images.
|
|
* Normal: Normal X image type. These are slow as they involve passing
|
|
* the entire image through the X connection each time a draw
|
|
* request is required. On Win32, a bitmap.
|
|
* Shared: Shared memory X image type. These are fast as the X server
|
|
* and the program actually use the same piece of memory. They
|
|
* should be used with care though as there is the possibility
|
|
* for both the X server and the program to be reading/writing
|
|
* the image simultaneously and producing undesired results.
|
|
* On Win32, also a bitmap.
