Method Details
-
createUI
Creates a new UI object for the given component.- Parameters:
c- component to create UI object for- Returns:
- the UI object
-
installUI
Configures the specified component appropriately for the look and feel. This method is invoked when theComponentUIinstance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:- Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
- Install a
LayoutManageron the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListeneron the component in order to detect and respond to component property changes appropriately. - Install keyboard UI (mnemonics, traversal, etc.) on the component.
- Initialize any appropriate instance data.
- Overrides:
installUIin classComponentUI- Parameters:
c- the component where this UI delegate is being installed- See Also:
-
getContext
Returns the Context for the specified component.- Specified by:
getContextin interfaceSynthUI- Parameters:
c- Component requesting SynthContext.- Returns:
- SynthContext describing component.
-
propertyChange
This method gets called when a bound property is changed.- Specified by:
propertyChangein interfacePropertyChangeListener- Parameters:
e- A PropertyChangeEvent object describing the event source and the property that has changed.
-
update
Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls thepaint(SynthContext,Graphics)method.In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the
paintmethod.- Overrides:
updatein classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- the component being painted- See Also:
-
getMinimumSize
The minimum size is the size of the display area plus insets plus the button.- Overrides:
getMinimumSizein classBasicComboBoxUI- Parameters:
c- the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimensionobject ornull - See Also:
-
paint
Paints the specified component according to the Look and Feel.This method is not used by Synth Look and Feel. Painting is handled by the
paint(SynthContext,Graphics)method.- Overrides:
paintin classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- the component being painted- See Also:
-
paint
Paints the specified component.- Parameters:
context- context for the component being paintedg- theGraphicsobject used for painting- See Also:
-
paintBorder
Paints the border.- Specified by:
paintBorderin interfaceSynthUI- Parameters:
context- a component contextg-Graphicsto paint onx- the X coordinatey- the Y coordinatew- width of the borderh- height of the border
-
paintCurrentValue
Paints the currently selected item.- Overrides:
paintCurrentValuein classBasicComboBoxUI- Parameters:
g- an instance ofGraphicsbounds- a bounding rectangle to render tohasFocus- is focused
-
getDefaultSize
Returns the default size of an empty display area of the combo box using the current renderer and font. This method was overridden to use SynthComboBoxRenderer instead of DefaultListCellRenderer as the default renderer when calculating the size of the combo box. This is used in the case of the combo not having any data.- Overrides:
getDefaultSizein classBasicComboBoxUI- Returns:
- the size of an empty display area
