2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here
