ScrollableT

GtkScrollable is an interface that is implemented by widgets with native scrolling ability.

To implement this interface you should override the hadjustment and vadjustment properties.

Creating a scrollable widget

All scrollable widgets should do the following.

- When a parent widget sets the scrollable child widget’s adjustments, the widget should populate the adjustments’ lower, upper, step-increment, page-increment and page-size properties and connect to the value-changed signal.

- Because its preferred size is the size for a fully expanded widget, the scrollable widget must be able to cope with underallocations. This means that it must accept any value passed to its gtk.WidgetClass.WidgetClass.size_allocate|gtk.WidgetClass.size_allocate function.

- When the parent allocates space to the scrollable child widget, the widget should update the adjustments’ properties with new values.

- When any of the adjustments emits the value-changed signal, the scrollable widget should scroll its contents.

template ScrollableT (

) {

}

getBorder bool getBorder(Border border): Returns the size of a non-scrolling border around the outside of the scrollable. An example for this would be treeview headers. GTK+ can use this information to display overlayed graphics, like the overshoot indication, at the right position.
getHadjustment Adjustment getHadjustment(): Retrieves the gtk.Adjustment used for horizontal scrolling.
getHscrollPolicy GtkScrollablePolicy getHscrollPolicy(): Gets the horizontal GtkScrollablePolicy
getScrollableStruct GtkScrollable* getScrollableStruct(bool transferOwnership): Get the main Gtk struct
getVadjustment Adjustment getVadjustment(): Retrieves the gtk.Adjustment used for vertical scrolling.
getVscrollPolicy GtkScrollablePolicy getVscrollPolicy(): Gets the vertical GtkScrollablePolicy
setHadjustment void setHadjustment(Adjustment hadjustment): Sets the horizontal adjustment of the GtkScrollable
setHscrollPolicy void setHscrollPolicy(GtkScrollablePolicy policy): Sets the GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.
setVadjustment void setVadjustment(Adjustment vadjustment): Sets the vertical adjustment of the GtkScrollable
setVscrollPolicy void setVscrollPolicy(GtkScrollablePolicy policy): Sets the GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
