public class ScrolledWindow
extends Bin

Add scrollbars to a Widget. There are times when you have a Widget which is larger than the area you wish to constrain it to, and the usual way to deal with this is to enhance the Widget with scrollbars. ScrolledWindow is a Bin which enables you to control the scrollbars added in such cases.

Some Widgets have built in support for scrolling; in such cases you add them directly with the usual add() method; however, if other Widgets need to be enhanced to support scrolling; in such cases you must nest it inside a Viewport; use addWithViewport() as a quick way to achieve this.

This is very poorly named. It is not a subclass of Window; it refers instead to a viewport scrolling around on an underlying canvas.

ScrolledWindow

public ScrolledWindow()

Construct a ScrolledWindow. This will automatically create default Adjustments for managing the horizontal and vertical ScrollBars.

Since:

4.0.3

add

public void add(Widget child)

Description copied from class: Container

Add a child Widget to this Container. This works for all the various Container types, of course, but most offer more specialized packing methods that allow you to control the positioning of the Widget being added with greater finesse.

Overrides:

add in class Container

addWithViewport

public void addWithViewport(Widget child)

Create a new Viewport and embeds the child Widget in it before adding it to the ScrolledWindow. This is a convenience function; you could always create the Viewport yourself if you really wanted. Note that this method is only for Widgets which do not support scrolling directly themselves; use add() directly for those Widgets that do.

As a convienience, calling this method will set the ShadowType of the created Viewport to NONE, meaning that if you do want a decoration, you can achieve it in a single place here with a call to ScrolledWindow's setShadowType().
