ScrollableIF

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 GtkWidgetClass.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.

interface ScrollableIF {

GtkScrollable* getScrollableTStruct();

void* getStruct();

Adjustment getHadjustment();

void setHadjustment(Adjustment hadjustment);

Adjustment getVadjustment();

void setVadjustment(Adjustment vadjustment);

GtkScrollablePolicy getHscrollPolicy();

void setHscrollPolicy(GtkScrollablePolicy policy);

GtkScrollablePolicy getVscrollPolicy();

void setVscrollPolicy(GtkScrollablePolicy policy);

}
