parent
- the parent compositeprefStore
- the preference store

Method Details
-
setBackground
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 classControl
- Parameters:
color
- the new color (or null)
-
setForeground
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 classControl
- Parameters:
color
- the new color (or null)
-
getForeground
Description copied from class:Control
Returns the foreground color that the receiver will use to draw.- Overrides:
getForeground
in classControl
- Returns:
- the receiver's foreground color
-
computeSize
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 befalse
, so layout manager caches can be retained.- Overrides:
computeSize
in classControl
- Parameters:
wHint
- the width hint (can beSWT.DEFAULT
)hHint
- the height hint (can beSWT.DEFAULT
)changed
-true
if the control's contents have changed, andfalse
otherwise- Returns:
- the preferred size of the control.
