make this special-case hscale/vscale details, so we can use it for
2001-06-03 Havoc Pennington <hp@pobox.com>
* gtk/gtkstyle.c (gtk_default_draw_slider): make this special-case
hscale/vscale details, so we can use it for scrollbar as well.
* tests/testgtk.c (reformat_value): honor digits from GtkScale
* gtk/gtkenums.h (GtkTroughType): Remove this enum
(GtkScrollType): add START and END from GtkTroughType
* gtk/gtkstyle.c (gtk_default_draw_slider): was not properly using
its x/y arguments
* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkscrollbar.h,
gtk/gtkscrollbar.c, gtk/gtkscale.h, gtk/gtkscale.c,
gtk/gtkhscrollbar.h, gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.h,
gtk/gtkvscrollbar.c, gtk/gtkhscale.h, gtk/gtkhscale.c,
gtk/gtkvscale.h, gtk/gtkvscale.c: Rewrite GtkRange and subclasses.
Notable changes in the process:
- stepper_size style property is the height for vertical
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.
- added getters for GtkScale setters
- middle-click begins a slider drag
