GtkAdjustment: Animated updates Add a private API that lets widget opt-in to animated updates of the adjustment value. When enabled, all calls to gtk_adjustment_set_value will smoothly transition from the old value to the new value, using a fixed easing function and a configurable duration. The animation is tied to the frame clock of the widget. By implementing this in GtkAdjustment, we can enable animation for both scrollbars and keybindings, which are often implemented in the child widget of the scrolled window. https://bugzilla.gnome.org/show_bug.cgi?id=732376 2014-06-30 22:09:50 +00:00			`/* GTK - The GIMP Toolkit`

GktAdjustment: Add explicit api for animated setting Making all set_value calls animated has side-effects, so we need to be more selective. 2014-07-02 21:55:20 +00:00			`void gtk_adjustment_animate_to_value (GtkAdjustment *adjustment,`

adjustment: Add private gtk_adjustment_get_target_value() method This call returns either the target value if there is an ongoing animation, or the current value if there is no animation. 2014-07-08 13:13:31 +00:00			`gdouble gtk_adjustment_get_target_value (GtkAdjustment *adjustment);`

textview: Avoid relocating adjustments on ::size-allocate while these are animating An animation may be scheduled while the textview content changed in size, so the resize queued would just unset the animation and set the adjusments with a current value, defeating gtk_text_view_scroll_to_iter(). In this case, just avoid the adjustment change, as there is a target value on the way. https://bugzilla.gnome.org/show_bug.cgi?id=733406 2014-07-21 19:16:32 +00:00			`gboolean gtk_adjustment_is_animating (GtkAdjustment *adjustment);`
