added args ::show_text, ::text_xalign, ::text_yalign, ::activity_mode.
Sun Nov 22 16:21:28 1998 Tim Janik <timj@gtk.org>
* gtk/gtkprogress.c: added args ::show_text, ::text_xalign,
::text_yalign, ::activity_mode.
* gtk/gtkprogressbar.c: added construct arg ::adjustment. added args
::bar_style, ::orientation, ::discrete_blocks, ::activity_step,
::activity_blocks.
(gtk_progress_bar_new):
(gtk_progress_bar_new_with_adjustment): use gtk_widget_new().
(gtk_progress_bar_construct): deprecated.
* gtk/gtkvscrollbar.c:
(gtk_vscrollbar_draw_step_back):
(gtk_vscrollbar_draw_step_forw): use "vscrollbar" as detail for
gtk_paint_arrow, to be consistent with hscrollbar.
* gtk/gtktext.c
added construct args ::hadjustment, ::vadjustment.
added args ::line_wrap, ::word_wrap.
(gtk_text_class_init): added scroll_adjustments signal.
(gtk_text_new): use gtk_widget_new.
(gtk_text_disconnect): remove adjustement with gtk_text_set_adjustments,
so we don't screw the reference counts and don't leave signals connected.
(gtk_text_destroy): disconnect adjustments signals.
(gtk_text_finalize): unref adjustments.
* gtk/gtkctree.c: added construct args ::n_columns and ::tree_column.
added args ::indent, ::spacing, ::show_stub, ::reorderable,
::use_drag_icons, ::line_style and ::expander_style.
(gtk_ctree_set_show_stub): renamed from gtk_ctree_show_stub, which is
deprecated now.
* gtk/gtkclist.h: remove GTK_CLIST_CONSTRUCT flag.
* gtk/gtkclist.c:
removed ::vadjustment and ::hadjustment args, introduced
::scroll_adjustments signal.
added ::shadow_type, ::selection_mode and ::row_height args.
added n_columns construct arg.
(gtk_clist_construct): call gtk_object_constructed().
(gtk_clist_set_row_height): if height is passed as 0,
revert to automatic height calculation.
(gtk_clist_destroy): before unrefing the adjustments, disconnect our
signal handlers.
Fri Nov 21 22:34:58 1998 Tim Janik <timj@gtk.org>
* gtk/gtkwidget.c (gtk_widget_new): call gtk_object_default_construct
like gtk_object_new.
(gtk_widget_destroy): assert that we only destroy constructed widgets.
* gtk/gtkobject.h (enum GtkArgFlags): new flag GTK_ARG_CONSTRUCT_ONLY
to identify args that may only be used for construction.
GTK_ARG_CONSTRUCT maybe used as normal arguments besides construction
time.
* gtk/gtkobject.c (gtk_object_new): invoke gtk_object_default_construct
at the end if the object is not fully constructed.
(gtk_object_newv): likewise.
(gtk_object_destroy): assert that we only destroy constructed objects.
(gtk_object_init): setup GTK_CONSTRUCTED from the
objects real klass.
(gtk_object_default_construct): new function to complete default
construction of an object by applying missing construtor args with
default values of 0, 0.0 or NULL.
(gtk_object_constructed): new function to mark an object as being
constructed (used from within constructors).
* gtk/gtkarg.c (gtk_arg_type_new_static): return the args info pointer
so it is immediatedly available for the caller.
* gtk/gtktypeutils.c (gtk_type_new): pass an object's real class to
the object initilizer (GtkObjectInitFunc takes a second arg now, the
real klass), and asure that object initializers may temporarily alter
the class pointer.
Fri Nov 20 08:00:30 1998 Tim Janik <timj@gtk.org>
* gtk/testgtk.c: change all occourances of gtk_container_add (
scrolled_window, widget) to gtk_scrolled_window_add_with_viewport (...)
for widget!=(clist, ctree, text, viewport).
* gtk/gtkcombo.c:
(gtk_combo_init): use gtk_scrolled_window_add_with_viewport()
to add children to the scrolled window.
* gtk/gtkscrolledwindow.h:
* gtk/gtkscrolledwindow.c:
changed scrolled_window->viewport to scrolled_window->child, and use
gtk_widget_scroll_adjustements() to set the scroll adjustments for the
widget, we do not create an additional viewport anymore.
added ::hadjustment and ::vadjustment constructor args.
(gtk_scrolled_window_new): use gtk_widget_new() to create the widget.
(gtk_scrolled_window_set_hadjustment):
(gtk_scrolled_window_set_vadjustment): new functions that superceed
gtk_scrolled_window_construct.
(gtk_scrolled_window_construct): deprecated this function.
* gtk/gtkhscrollbar.c:
* gtk/gtkvscrollbar.c:
* gtk/gtkhscale.c:
* gtk/gtkvscale.c:
support a constructor arg "::adjustment", and use gtk_widget_new() for
the widget creation.
* gtk/gtkrange.c: added ::update_policy arg.
(gtk_range_set_adjustment): if adjustment is passed in as NULL, create
a default adjustment so this function can be used for derived widgets
that depend on the adjustment's existance.
(gtk_range_destroy): disconnect the adjustment signal, so we don't
get called after we got destroyed, we don't destroy the adjustment
in here, because it might have been provided from another widget.
* gtk/gtkviewport.c: introduced ::scroll_adjustments signal.
(gtk_viewport_destroy): same as gtk_range_destroy.
* gtk/gtkprogress.c (gtk_progress_destroy): same as gtk_range_destroy.
* gtk/gtkwidget.h:
* gtk/gtkwidget.c: changed gtk_widget_activate() to return a
gboolean, indicating whether this widget supports activation.
added gtk_widget_scroll_adjustements() to set the scrolling
adjustments of a widget.
Wed Nov 19 01:22:42 1998 Tim Janik <timj@gtk.org>
* gtk/gtkoptionmenu.c:
(gtk_option_menu_remove_contents):
(gtk_option_menu_update_contents): removed
gtk_container_[un]block_resize() pairs.
* gtk/gtknotebook.h:
* gtk/gtknotebook.c: removed the tab_border field, since it shouldn't
be used outside of gtknotebook.c anyways. made ARG_TAB_BORDER a
wrtie-only argument.
* *.c: made deprecated functions issue a message:
gtk_clist_set_border, gtk_container_block_resize,
gtk_container_unblock_resize, gtk_container_need_resize,
gtk_object_class_add_user_signal, gtk_spin_button_construct,
gtk_scrolled_window_construct.
removed non-functional functions:
gtk_container_disable_resize, gtk_container_enable_resize,
gtk_clist_set_policy.
Wed Nov 18 22:54:36 1998 Tim Janik <timj@gtk.org>
* gtk/gtkbox.c (gtk_box_init):
* gtk/gtkdrawingarea.c (gtk_drawing_area_init):
* gtk/gtkeventbox.c (gtk_event_box_init):
* gtk/gtkfixed.c (gtk_fixed_init):
* gtk/gtkframe.c (gtk_frame_init):
* gtk/gtkhandlebox.c (gtk_handle_box_init):
* gtk/gtkpacker.c (gtk_packer_init):
* gtk/gtkmisc.c (gtk_misc_init):
* gtk/gtkpreview.c (gtk_preview_init):
* gtk/gtkprogress.c (gtk_progress_init):
