public class ToolBar extends Composite
The item children that may be added to instances of this class
must be of type ToolItem.
Note that although this class is a subclass of Composite,
it does not make sense to add Control children to it,
or set a layout on it.
Note: Only one of the styles HORIZONTAL and VERTICAL may be specified.
IMPORTANT: This class is not intended to be subclassed.
| Constructor and Description |
|---|
ToolBar(Composite parent,
int style)
Constructs a new instance of this class given its parent
and a style value describing its behavior and appearance.
|
| Modifier and Type | Method and Description |
|---|---|
Point |
computeSize(int wHint,
int hHint,
boolean changed)
Returns the preferred size of the receiver.
|
<T> T |
getAdapter(java.lang.Class<T> adapter)
Implementation of the
Adaptable interface. |
ToolItem |
getItem(int index)
Returns the item at the given, zero-relative index in the
receiver.
|
ToolItem |
getItem(Point point)
Returns the item at the given point in the receiver
or null if no such item exists.
|
int |
getItemCount()
Returns the number of items contained in the receiver.
|
ToolItem[] |
getItems()
Returns an array of
ToolItems which are the items
in the receiver. |
int |
getRowCount()
Returns the number of rows in the receiver.
|
int |
indexOf(ToolItem item)
Searches the receiver's list starting at the first item
(index 0) until an item is found that is equal to the
argument, and returns the index of that item.
|
void |
setBounds(Rectangle bounds)
Sets the receiver's size and location to the rectangular
area specified by the argument.
|
void |
setFont(Font font)
Sets the font that the receiver will use to paint textual information
to the font specified by the argument, or to the default font for that
kind of control if the argument is null.

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.

Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver.

Control
The preferred size of a control is the size that it would
best be displayed at. The width hint and height hint arguments
allow the caller to ask a control questions such as "Given a particular
width, how high does the control need to be to show all of the contents?"
To indicate that the caller does not wish to constrain a particular
dimension, the constant SWT.DEFAULT is passed for the hint.
If the changed flag is true, it indicates that the receiver's
contents have changed, therefore any caches that a layout manager
containing the control may have been keeping need to be flushed. When the
control is resized, the changed flag will be false, so layout
manager caches can be retained.

Controlx and
y fields of the rectangle are relative to
the receiver's parent (or its display if its parent is null).
Note: Attempting to set the width or height of the receiver to a negative number will cause that value to be set to zero instead.
