Description

The Viewport 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 Grid, Box, and so on.

If a widget has native scrolling abilities, such as TextView, TreeView or IconView, it can be added to a ScrolledWindow with containerAdd. If a widget does not, you must first add the widget to a Viewport, then add the viewport to the scrolled window. containerAdd does this automatically if a child that does not implement Scrollable is added to a ScrolledWindow, 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.

No description available in the introspection data.

constructViewportShadowType :: IsViewport o => ShadowType -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “shadow-type” property. This is rarely needed directly, but it is used by new.

getViewportShadowType :: (MonadIO m, IsViewport o) => o -> m ShadowType Source #

Get the value of the “shadow-type” property. When overloading is enabled, this is equivalent to

get viewport #shadowType

setViewportShadowType :: (MonadIO m, IsViewport o) => o -> ShadowType -> m () Source #

Set the value of the “shadow-type” property. When overloading is enabled, this is equivalent to

set viewport [ #shadowType := value ]
