public class CBanner
extends Composite

Instances of this class implement a Composite that lays out its children and allows programmatic control of the layout. It draws a separator between the left and right children which can be dragged to resize the right control. CBanner is used in the workbench to layout the toolbar area and perspective switching toolbar.

Note that although this class is a subclass of Composite, it does not make sense to set a layout on it.

Styles:
NONE
Events:
(None)

IMPORTANT: This class is not intended to be subclassed.

Since:
1.0

Constructor Detail

CBanner

public CBanner(
Composite parent,
               int style)
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

Parameters:
parent - a widget which will be the parent of the new instance (cannot be null)
style - the style of widget to construct
Throws:
IllegalArgumentException -
  • ERROR_NULL_ARGUMENT - if the parent is null
