Constructor Detail

GestureCategoryDisplay

public GestureCategoryDisplay()

GestureCategoryDisplay

public GestureCategoryDisplay(GestureCategory gc)

GestureCategoryDisplay

public GestureCategoryDisplay(GestureCategory gc,
                              boolean showAuthor)

Method Detail

setGestureCategory

public void setGestureCategory(GestureCategory gc)

getGestureCategory

public GestureCategory getGestureCategory()

update

public void update(Observable o,
                   Object arg)

Specified by:

update in interface Observer

addGesture

public GestureDisplay addGesture(Gesture gesture)

Causes the entire frame to be repacked to make sure that the new GestureDisplay is properly drawn. This seems wasteful, but nothing else worked.

initUI

protected void initUI()

one-time setup when the widget is made

rebuildUI

public void rebuildUI()

If the gesturecategory changes, need to change the gestures that are displayed.

isOpaque

public boolean isOpaque()

Overrides:

isOpaque in class JComponent

getSelectionDisplay

public GestureDisplay getSelectionDisplay()

Returns GestureDisplay associated with current selection (or null if none).

getSelection

public Gesture getSelection()

Returns currently selected Gesture (or null if none).

getSelectedObjects

public Object[] getSelectedObjects()

Returns currently selected Gestures (or null if none). For now this will always be an array of 1 Gesture.

Specified by:

getSelectedObjects in interface ItemSelectable

isOptimizedDrawingEnabled

public boolean isOptimizedDrawingEnabled()

This component does tile its children

Overrides:

isOptimizedDrawingEnabled in class JComponent

narrow

public void narrow(Vector gestures,
                   String reason)

Narrows to the specified gestures (which should be a Vector of Gesture). The reason is for inclusion in the frame title.

addItemListener

public void addItemListener(ItemListener l)

Specified by:

addItemListener in interface ItemSelectable

removeItemListener

public void removeItemListener(ItemListener l)

Specified by:

removeItemListener in interface ItemSelectable

fireItemChange

protected void fireItemChange(int type,
                              Gesture item,
                              int selectState)

setAuthorVisible

public void setAuthorVisible(boolean on)
