GtkViewportA container for adding scrolling capabilities to widgets without native scrolling support.
Hierarquia de Objetos
A GtkViewport provides scrolling capabilities to widgets that don't support native scrolling. E.g., a GtkLabel or a GtkVBox could be packed into a GtkScrolledWindow, but since the classes don't support the "set-scroll-adjustments" signal, using the scrollbars wouldn't work.
A viewport also takes care to show only a certain part of the widget, hiding the rest of it that is not in the visible area.
get_hadjustment() Returns the horizontal adjustment. get_shadow_type() Returns the shadow type. get_vadjustment() Returns the vertical adjustment. set_hadjustment() Sets the horizontal adjustment. set_shadow_type() Sets the shadow type. set_vadjustment() Sets the vertical adjustment.
Use os métodos get_property e set_property para acessar estes.
hadjustment: Horizontal adjustment. shadow-type: Shadow type. vadjustment: Vertical adjustment
"set-scroll-adjustments" One or both adjustments are changed.
