public class ToolBar extends Composite
The item children that may be added to instances of this class
must be of type
Note that although this class is a subclass of
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|
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

Returns the preferred size of the receiver.
Implementation of the
Returns the item at the given, zero-relative index in the receiver.
Returns the item at the given point in the receiver or null if no such item exists.
Returns the number of items contained in the receiver.
Returns an array of
Returns the number of rows in the receiver.
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.
Sets the receiver's size and location to the rectangular area specified by the argument.
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.

public ToolBar(Composite parent, int style)
The style value is either one of the style constants defined in
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
SWT style constants. The class description
lists the style constants that are applicable to the class.
Style bits are also inherited from superclasses.
parent- a composite control which will be the parent of the new instance (cannot be null)
style- the style of control to construct
public <T> T getAdapter(java.lang.Class<T> adapter)
IMPORTANT: This method is not part of the RWT public API. It is marked public only so that it can be shared within the packages provided by RWT. It should never be accessed from application code.
public ToolItem getItem(int index)
index- the index of the item to return
point- the point used to locate the item
public int getItemCount()
public ToolItem getItems()
ToolItems which are the items in the receiver.
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.
public int indexOf(ToolItem item)
item- the search item
public Point computeSize(int wHint, int hHint, boolean changed)
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.
wHint- the width hint (can be
hHint- the height hint (can be
trueif the control's contents have changed, and
Control.pack(boolean), "computeTrim, getClientArea for controls that implement them"
public int getRowCount()
WRAPstyle, the number of rows can be greater than one. Otherwise, the number of rows is always one.
public void setBounds(Rectangle bounds)
yfields 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.
