ScrollableT

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

To implement this interface you should override the #GtkScrollable:hadjustment and #GtkScrollable: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’ #GtkAdjustment:lower, #GtkAdjustment:upper, #GtkAdjustment:step-increment, #GtkAdjustment:page-increment and #GtkAdjustment:page-size properties and connect to the #GtkAdjustment::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 #GtkAdjustment::value-changed signal, the scrollable widget should scroll its contents.

bool getBorder(Border border)

getHadjustment
Adjustment getHadjustment()

Retrieves the #GtkAdjustment used for horizontal scrolling.

getHscrollPolicy
GtkScrollablePolicy getHscrollPolicy()

Gets the horizontal #GtkScrollablePolicy.

getScrollableStruct
GtkScrollable* getScrollableStruct()

Get the main Gtk struct

getVadjustment
Adjustment getVadjustment()

Retrieves the #GtkAdjustment 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.
