Constructors

this
this(ToolBar parent, int style)

Constructs a new instance of this class given its parent (which must be a <code>ToolBar</code>) and a style value describing its behavior and appearance. The item is added to the end of the items maintained by its parent. <p> 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 <em>bitwise OR</em>'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. </p>

this
this(ToolBar parent, int style, int index)

Constructs a new instance of this class given its parent (which must be a <code>ToolBar</code>), a style value describing its behavior and appearance, and the index at which to place it in the items maintained by its parent. <p> 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 <em>bitwise OR</em>'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. </p>

Functions

addSelectionListener
void addSelectionListener(SelectionListener listener)

Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in the <code>SelectionListener</code> interface. <p> When <code>widgetSelected</code> is called when the mouse is over the arrow portion of a drop-down tool, the event object detail field contains the value <code>SWT.ARROW</code>. <code>widgetDefaultSelected</code> is not called. </p>

getBounds
Rectangle getBounds()

Returns a rectangle describing the receiver's size and location relative to its parent.

getControl
Control getControl()

Returns the control that is used to fill the bounds of the item when the item is a <code>SEPARATOR</code>.

getDisabledImage
Image getDisabledImage()

Returns the receiver's disabled image if it has one, or null if it does not. <p> The disabled image is displayed when the receiver is disabled. </p>

getEnabled
bool getEnabled()

Returns <code>true</code> if the receiver is enabled, and <code>false</code> otherwise. A disabled control is typically not selectable from the user interface and draws with an inactive or "grayed" look.

getHotImage
Image getHotImage()

Returns the receiver's hot image if it has one, or null if it does not. <p> The hot image is displayed when the mouse enters the receiver. </p>

getParent
ToolBar getParent()

Returns the receiver's parent, which must be a <code>ToolBar</code>.

getSelection
bool getSelection()

Returns <code>true</code> if the receiver is selected, and false otherwise. <p> When the receiver is of type <code>CHECK</code> or <code>RADIO</code>, it is selected when it is checked (which some platforms draw as a pushed in button). If the receiver is of any other type, this method returns false. </p>

getToolTipText
String getToolTipText()

Returns the receiver's tool tip text, or null if it has not been set.

getWidth
int getWidth()

Gets the width of the receiver.

isEnabled
bool isEnabled()

Returns <code>true</code> if the receiver is enabled and all of the receiver's ancestors are enabled, and <code>false</code> otherwise. A disabled control is typically not selectable from the user interface and draws with an inactive or "grayed" look.

removeSelectionListener
void removeSelectionListener(SelectionListener listener)

Removes the listener from the collection of listeners who will be notified when the control is selected by the user.

setControl
void setControl(Control control)

Sets the control that is used to fill the bounds of the item when the item is a <code>SEPARATOR</code>.

setDisabledImage
void setDisabledImage(Image image)

Sets the receiver's disabled image to the argument, which may be null indicating that no disabled image should be displayed. <p> The disabled image is displayed when the receiver is disabled. </p>

setEnabled
void setEnabled(bool enabled)

Enables the receiver if the argument is <code>true</code>, and disables it otherwise. <p> A disabled control is typically not selectable from the user interface and draws with an inactive or "grayed" look. </p>

setHotImage
void setHotImage(Image image)

Sets the receiver's hot image to the argument, which may be null indicating that no hot image should be displayed. <p> The hot image is displayed when the mouse enters the receiver. </p>

setSelection
void setSelection(bool selected)

Sets the selection state of the receiver. <p> When the receiver is of type <code>CHECK</code> or <code>RADIO</code>, it is selected when it is checked (which some platforms draw as a pushed in button). </p>

setText
void setText(String string)

Sets the receiver's text. The string may include the mnemonic character. </p> <p> Mnemonics are indicated by an '&amp;' that causes the next character to be the mnemonic. When the user presses a key sequence that matches the mnemonic, a selection event occurs. On most platforms, the mnemonic appears underlined but may be emphasised in a platform specific manner. The mnemonic indicator character '&amp;' can be escaped by doubling it in the string, causing a single '&amp;' to be displayed. </p>

setToolTipText
void setToolTipText(String string)

Sets the receiver's tool tip text to the argument, which may be null indicating that no tool tip text should be shown.

setWidth
void setWidth(int width)

Sets the width of the receiver, for <code>SEPARATOR</code> ToolItems.
