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/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.

Notable changes in the process:

ranges, width for horizontal; the other dimension matches
the trough size
- add ability to do NeXT-style steppers (and several other styles
that don't make any sense)
- added min_slider_length, fixed_slider_length properties to
GtkScrollbar
- cleaned some private (or at least useless) functions out of
gtkscale.h
- moved bindings to GtkScale from subclasses, even arrow keys,
since blind users don't know scale orientation.
- change move_slider action signal to use new GtkScrollType,
remove GtkTroughType argument
- digits rounds the values a range will input to the given
number of decimals, but will not try to force adjustment
values set by other controllers. That is, we no longer
modify adjustment->value inside a value_changed handler.

(gtk_text_layout_move_iter_to_next_line): fix these two for
invisible text, lots of other stuff still hosed.
* gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook):
new function, replaces the get/set palette stuff. This function
is intended for use by libgnomeui which should set the hook to a
thing which sets the palette in GConf, and we need the
GConf-to-xsettings proxy which will result in the change being
propagated back to the GTK app.

about unusable signals that it may be because the signal has
parameters.

it.
(gtk_widget_modify_color_component): call
gtk_widget_modify_style() so the rc style will get copied.
(gtk_widget_modify_font): ditto
* gtk/gtkrc.c: make a couple variables static

help button by default, since it does nothing

around with UI

so we can have tooltips
* gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we
can have tooltips

GDK_ENABLE_BROKEN, because its memory behavior is completely
hosed.

binding set, add numeric keypad support
* gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete
* gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms

addition to plain Delete

GDK_KP_Enter in addition to GDK_Return
* gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to
activate on entry instead of key press
(gtk_font_selection_on_clist_key_press): get
rid of this signal handler, not needed with new font sel.
* gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a
no-longer-needed emit_stop_by_name(), just return TRUE
* gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings
cruft, this widget is no longer focusable.
* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c,
gtk/gtkhscale.c: Get rid of trough_keys virtual function, add
move_slider action signal, add binding set for vscale/hscale, in
the process support numeric keypad
* gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings;
make GDK_Return and GDK_KP_Enter activate the entry via
binding set, instead of hardcoded.

Provide information about how an adjustment change in a range widget
Thu Aug 26 22:44:12 2004 Matthias Clasen <maclas@gmx.de>
Provide information about how an adjustment change in a range
widget happened. Add a "slider-moved" signal which reports how
a user is interacting with the range, whether they are clicking
on a stepper or the trough, or dragging the slider. (#133263,
Thomas Fitzsimmons)
* gtk/gtkmarshalers.list: Add signal type BOOLEAN:ENUM,DOUBLE.
* gtk/gtkrange.c (gtk_range_class_init): Add "change-value"
signal.
(gtk_range_internal_set_value): Rename to
gtk_range_real_change_value. Add GtkScrollType parameter. Emit
the change-value signal when the range's value changes.
(update_slider_position, gtk_range_scroll_event, step_back,
step_forward, page_back, page_forward, scroll_begin,
scroll_end): Change gtk_range_internal_set_value to
gtk_range_real_change_value.
* gtk/gtkrange.h (struct _GtkRangeClass): Declare change_value
function.
