computeSize

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

Description copied from class: Control

Returns the preferred size (in points) 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.

Overrides:

computeSize in class Control

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.

addMouseListener

public void addMouseListener(MouseListener l)

Description copied from class: Control

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.

Overrides:

addMouseListener in class Control

Parameters:

l - the listener which should be notified

See Also:

• MouseListener
• Control.removeMouseListener(org.eclipse.swt.events.MouseListener)

addMouseTrackListener

public void addMouseTrackListener(MouseTrackListener l)

Description copied from class: Control

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.

Overrides:

addMouseTrackListener in class Control

Parameters:

l - the listener which should be notified

See Also:

• MouseTrackListener
• Control.removeMouseTrackListener(org.eclipse.swt.events.MouseTrackListener)

addPaintListener

public void addPaintListener(PaintListener l)

Description copied from class: Control

Adds the listener to the collection of listeners who will be notified when the receiver needs to be painted, by sending it one of the messages defined in the PaintListener interface.

Overrides:

addPaintListener in class Control

Parameters:

l - the listener which should be notified

• PaintListener
• Control.removePaintListener(org.eclipse.swt.events.PaintListener)

setBackground

public void setBackground(Color c)

Description copied from class: Control

Sets the receiver's background color to the color specified by the argument, or to the default system color for the control if the argument is null.

Note: This operation is a hint and may be overridden by the platform.

Overrides:

setBackground in class Control

Parameters:

c - the new color (or null)

setForeground

public void setForeground(Color c)

Description copied from class: Control

Sets the receiver's foreground color to the color specified by the argument, or to the default system color for the control if the argument is null.

Note: This operation is a hint and may be overridden by the platform.

Overrides:

setForeground in class Control

Parameters:

c - the new color (or null)

setCursor

public void setCursor(Cursor c)

Description copied from class: Control

Sets the receiver's cursor to the cursor specified by the argument, or to the default cursor for that kind of control if the argument is null.

When the mouse pointer passes over a control its appearance is changed to match the control's cursor.

Overrides:

setCursor in class Control

Parameters:

c - the new cursor (or null)
