Viewport

The #GtkViewport widget acts as an adaptor class, implementing scrollability for child widgets that lack their own scrolling capabilities. Use GtkViewport to scroll child widgets such as #GtkGrid, #GtkBox, and so on.

If a widget has native scrolling abilities, such as #GtkTextView, #GtkTreeView or #GtkIconView, it can be added to a #GtkScrolledWindow with gtk_container_add(). If a widget does not, you must first add the widget to a #GtkViewport, then add the viewport to the scrolled window. gtk_container_add() does this automatically if a child that does not implement #GtkScrollable is added to a #GtkScrolledWindow, so you can ignore the presence of the viewport.

The GtkViewport will start scrolling content only if allocated less than the child widget’s minimum size in a given orientation.

CSS nodes

GtkViewport has a single CSS node with name viewport.

class Viewport : Bin , ScrollableIF {

protected

GtkViewport* gtkViewport;

GtkViewport* getViewportStruct();

void* getStruct();

void setStruct(GObject* obj);

this(GtkViewport* gtkViewport, bool ownedRef);

mixin ScrollableT!(GtkViewport) ;

static GType getType();

this(Adjustment hadjustment, Adjustment vadjustment);

Window getBinWindow();

Adjustment getHadjustment();

GtkShadowType getShadowType();

Adjustment getVadjustment();

Window getViewWindow();

void setHadjustment(Adjustment adjustment);

void setShadowType(GtkShadowType type);

void setVadjustment(Adjustment adjustment);

}

Constructors

this this(GtkViewport* gtkViewport, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(Adjustment hadjustment, Adjustment vadjustment): Creates a new #GtkViewport with the given adjustments, or with default adjustments if none are given.

Functions

getBinWindow Window getBinWindow(): Gets the bin window of the #GtkViewport.
getHadjustment Adjustment getHadjustment(): Returns the horizontal adjustment of the viewport.
getShadowType GtkShadowType getShadowType(): Gets the shadow type of the #GtkViewport. See gtk_viewport_set_shadow_type().
getStruct void* getStruct(): the main Gtk struct as a void*
getVadjustment Adjustment getVadjustment(): Returns the vertical adjustment of the viewport.
getViewWindow Window getViewWindow(): Gets the view window of the #GtkViewport.
getViewportStruct GtkViewport* getViewportStruct(): Get the main Gtk struct
setHadjustment void setHadjustment(Adjustment adjustment): Sets the horizontal adjustment of the viewport.
setShadowType void setShadowType(GtkShadowType type): Sets the shadow type of the viewport.
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
setVadjustment void setVadjustment(Adjustment adjustment): Sets the vertical adjustment of the viewport.

Mixins

__anonymous mixin ScrollableT!(GtkViewport): Undocumented in source.

Variables

Inherited Members

From Bin

gtkBin GtkBin* gtkBin;: the main Gtk struct
getBinStruct GtkBin* getBinStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
getType GType getType()
getChild Widget getChild(): Gets the child of the #GtkBin, or %NULL if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

From ScrollableIF

getScrollableStruct GtkScrollable* getScrollableStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
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 #GtkAdjustment used for horizontal scrolling.
getHscrollPolicy GtkScrollablePolicy getHscrollPolicy(): Gets the horizontal #GtkScrollablePolicy.
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.
