gtk.scrollable
Module for [Scrollable] interface
Types 2
interfaceScrollable
#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.
Methods
gtk.adjustment.Adjustment hadjustment() @propertyGet `hadjustment` property. Returns: Horizontal #GtkAdjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.void hadjustment(gtk.adjustment.Adjustment propval) @propertySet `hadjustment` property. Params: propval = Horizontal #GtkAdjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.gtk.types.ScrollablePolicy hscrollPolicy() @propertyGet `hscrollPolicy` property. Returns: Determines whether horizontal scrolling should start once the scrollable widget is allocated less than its minimum width or less than its natural width.void hscrollPolicy(gtk.types.ScrollablePolicy propval) @propertySet `hscrollPolicy` property. Params: propval = Determines whether horizontal scrolling should start once the scrollable widget is allocated less than its minimum width or less than its natural width.gtk.adjustment.Adjustment vadjustment() @propertyGet `vadjustment` property. Returns: Verical #GtkAdjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.void vadjustment(gtk.adjustment.Adjustment propval) @propertySet `vadjustment` property. Params: propval = Verical #GtkAdjustment of the scrollable widget. This adjustment is shared between the scrollable widget and its parent.gtk.types.ScrollablePolicy vscrollPolicy() @propertyGet `vscrollPolicy` property. Returns: Determines whether vertical scrolling should start once the scrollable widget is allocated less than its minimum height or less than its natural height.void vscrollPolicy(gtk.types.ScrollablePolicy propval) @propertySet `vscrollPolicy` property. Params: propval = Determines whether vertical scrolling should start once the scrollable widget is allocated less than its minimum height or less than its natural height.bool getBorder(out gtk.border.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...gtk.adjustment.Adjustment getHadjustment()Retrieves the #GtkAdjustment used for horizontal scrolling. Returns: horizontal #GtkAdjustment.gtk.types.ScrollablePolicy getHscrollPolicy()Gets the horizontal #GtkScrollablePolicy. Returns: The horizontal #GtkScrollablePolicy.gtk.adjustment.Adjustment getVadjustment()Retrieves the #GtkAdjustment used for vertical scrolling. Returns: vertical #GtkAdjustment.gtk.types.ScrollablePolicy getVscrollPolicy()Gets the vertical #GtkScrollablePolicy. Returns: The vertical #GtkScrollablePolicy.void setHadjustment(gtk.adjustment.Adjustment hadjustment = null)Sets the horizontal adjustment of the #GtkScrollable.void setHscrollPolicy(gtk.types.ScrollablePolicy policy)Sets the #GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.void setVadjustment(gtk.adjustment.Adjustment vadjustment = null)Sets the vertical adjustment of the #GtkScrollable.void setVscrollPolicy(gtk.types.ScrollablePolicy policy)Sets the #GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.interfaceScrollableGidBuilderImpl(T)
