Constructors

this this(ExpandBar 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 <code>SWT</code> which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the <code>int</code> "|" operator) two or more of those <code>SWT</code> style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.
this this(ExpandBar parent, int style, int index): Constructs a new instance of this class given its parent, a style value describing its behavior and appearance, and the index at which to place it in the items maintained by its parent. The style value is either one of the style constants defined in class <code>SWT</code> which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the <code>int</code> "|" operator) two or more of those <code>SWT</code> style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

Functions

getControl Control getControl(): Returns the control that is shown when the item is expanded. If no control has been set, return <code>null</code>.
getExpanded bool getExpanded(): Returns <code>true</code> if the receiver is expanded, and false otherwise.
getHeaderHeight int getHeaderHeight(): Returns the height of the receiver's header
getHeight int getHeight(): Gets the height of the receiver.
getParent ExpandBar getParent(): Returns the receiver's parent, which must be a <code>ExpandBar</code>.
setControl void setControl(Control control): Sets the control that is shown when the item is expanded.
setExpanded void setExpanded(bool expanded): Sets the expanded state of the receiver.
setHeight void setHeight(int height): Sets the height of the receiver. This is height of the item when it is expanded, excluding the height of the header.
