Control

Control()

Prevents uninitialized instances from being created outside the package.

Control

public Control(Composite parent,
               int style)

Enabled: 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 composite control which will be the parent of the new instance (cannot be null)

style - the style of control to construct

See Also:

SWT.BORDER, Widget.checkSubclass(), Widget.getStyle()

See Also:

KeyListener, removeKeyListener(org.eclipse.swt.events.KeyListener)

addMouseListener

public void addMouseListener(MouseListener listener)

Enabled: Adds the listener to the collection of listeners who will be notified when mouse buttons are pressed and released, by sending it one of the messages defined in the MouseListener interface.

Parameters:

See Also:

MouseListener, removeMouseListener(org.eclipse.swt.events.MouseListener)

addMouseTrackListener

public void addMouseTrackListener(MouseTrackListener listener)

Enabled: Adds the listener to the collection of listeners who will be notified when the mouse passes or hovers over controls, by sending it one of the messages defined in the MouseTrackListener interface.

Parameters:

listener - the listener which should be notified

See Also:

MouseTrackListener, removeMouseTrackListener(org.eclipse.swt.events.MouseTrackListener)

addMouseMoveListener

computeSize

public Point computeSize(int wHint,
                         int hHint)

Enabled: Returns the preferred size of the receiver.

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.

Parameters:

wHint - the width hint (can be SWT.DEFAULT)

hHint - the height hint (can be SWT.DEFAULT)

Returns:

the preferred size of the control

computeSize

public Point computeSize(int wHint,
                         int hHint,
                         boolean changed)

Enabled: Returns the preferred size of the receiver.

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.

Parameters:

wHint - the width hint (can be SWT.DEFAULT)

hHint - the height hint (can be SWT.DEFAULT)

changed - true if the control's contents have changed, and false otherwise

Returns:

the preferred size of the control.

destroyWidget

void destroyWidget()

Description copied from class: Widget

Destroys the widget in the operating system and releases the widget's handle. If the widget does not have a handle, this method may hide the widget, mark the widget as destroyed or do nothing, depending on the widget.

When a widget is destroyed in the operating system, its descendents are also destroyed by the operating system. This means that it is only necessary to call destroyWidget on the root of the widget tree.

This method is called after releaseWidget.

Overrides:

destroyWidget in class Widget
