Sets our main struct and passes it to the parent class
Creates a new GtkViewport with the given adjustments, or with default adjustments if none are given.
Gets the bin window of the GtkViewport. Since 2.20
Gets the shadow type of the GtkViewport. See gtk_viewport_set_shadow_type().
the main Gtk struct as a void*
Gets the view window of the GtkViewport. Since 2.22
Sets the shadow type of the viewport.
the main Gtk struct
the main Gtk struct
the main Gtk struct as a void*
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.
the main Gtk struct as a void*
Retrieves the GtkAdjustment used for horizontal scrolling.
Sets the horizontal adjustment of the GtkScrollable.
Retrieves the GtkAdjustment used for vertical scrolling.
Sets the vertical adjustment of the GtkScrollable.
Gets the horizontal GtkScrollablePolicy.
Sets the GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.
Gets the vertical GtkScrollablePolicy.
Sets the GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
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.
