The adjustment value being equal is checked by
gtk_adjustment_set_value() and the necessity of calc_layout() is handled
by the value_changed signal handler.
Css margin now works on the slider as they do on the trough.
The margin is not considered in the space allocation as it is for
the trough, so the slider width will be the set slider-width -
margins. Spefifying margins on the main widget in the css will
clearly affect both the trough and the slider, so theme changes are
needed.
This will be used to identify a scrollbar is being dragged - we
don't actually need the style class; another way to keep track
of the dragging status would be ok too.
The scale in the selectable listbox in page 2 of gtk3-widget-factory
has the flaw that the row is getting selected even when one only
interacts with the scale - unlike e.g. the checkbutton and button
further down in the listbox.
The problem is that GtkRange is trying to claim the sequence for
the drag gesture from the ::pressed handler of a multipress
gesture. Since the drag gesture hasn't seen the sequence at this
point, that is ineffective.
The fix here is to rearrange the gestures so that the multipress
gesture sees the sequence before the drag gesture, and then
claim the sequence from the ::drag-begin handler.
This is a temporary workaround for scrolling units being amplified
on quartz, due to the assumption that smooth scrolling deltas are
always in some abstract unit similar to the one from xi2.
A proper solution for the situation is described in bug #736121, but
since we are close to release, this patch solves the issue temporarily.

... in places where we draw a background. This was changed for GTK 3.0.0
to allow animations, but these days it doesn't make sense anymore to use
gtk_render_activity() for backgrounds.
That gesture is meant to handle clicks from several buttons, so unset
the new GDK_BUTTON_PRIMARY default. Also, remove unnecessary boilerplate
with the new default values.

If the drag gesture gets a GtkGesture::updated signal, the user
is directly interacting through pointer/touch with the range slider,
animating the adjustment value change in this situation can produce
perceived lag, so set the value immediately when this is happening.
Resize grips were introduced for GNOME 3.0, before we had any of the
"new GNOME app" features like invisible borders and CSD. With OS X 10.6
and 10.7, Apple has replaced the classic grips in their applications
with invisible borders as well.
New GNOME app designs don't use resize grips anymore and the new
default theme for GTK+, Adwaita, disables them entirely by forcing their
width and height to 0.
They're past their time. Remove the code to support them. This can
always be reverted if some app relies on them.
A multipress gesture takes care of clicks, and where those happened.
If the click is meant to move the slider while pressed, the drag gesture
takes over, dragging the slider while active.
Event controllers now auto-attach, and the GtkCapturePhase only determines
when are events dispatched, but all controllers are managed by the widget wrt
grabs.
All callers have been updated.
The propagation phase property/methods in GtkEventController are gone,
This is now set directly on the GtkWidget add/remove controller API,
which has been made private.
The only public bit now are the new functions gtk_gesture_attach() and
gtk_gesture_detach() that will use the private API underneath.
All callers have been updated.
If a range goes all the way to the edge of the screen then we don't
have any way to activate autoscrolling. By adding a small region
at the ends of the range we can handle this case. This is the same
approach used in treeviews.
A problem with the zoom scroll mode is that you have to restart
if you hit the bottom of the screen before you hit the bottom
of your document.
This commit adds an autoscroll feature to the zoom scroll: if
you move outside the window while in zoom scroll mode, we keep
scrolling in the direction you were going until you let go
of the mouse button.

Triggering zoom scroll mode by Shift click was too much
of an easter egg. It also requires using keyboard and
mouse together, which is hard to do for many users.
Instead, we now trigger zoom scroll mode by click-and-hold
(or touch-and-hold).
