Method Detail

selectionMode

int selectionMode(MouseEvent aMouseEvent)

Returns how a list of potentially selected objects is to be changed into the selection.

Parameters:

aMouseEvent - the mouse event that triggered the selection

Returns:

one of ILcdGXYSelectControllerModel.FIRST_TOUCHED, ILcdGXYSelectControllerModel.ALTERNATE or ILcdGXYSelectControllerModel.CHOOSE. If ALTERNATE, a new selection combination is made for each mousePressed event done at the same screen location. If FIRST_TOUCHED, the first Object touched on a mousePressed event is selected. If CHOOSE, the choice of the selection is delegated to chooseSelectionAt(com.luciad.view.gxy.ILcdGXYLayerSubsetList, java.awt.event.MouseEvent, com.luciad.view.gxy.ILcdGXYView).

chooseSelectionAt

void chooseSelectionAt(ILcdGXYLayerSubsetList aPotentialSelection,
                       MouseEvent aMouseEvent,
                       ILcdGXYView aGXYView)

Chooses and sets the selection considering the Objects touched by a given mousePressed event. aPotentialSelection contains these touched Objects and is passed by the TLcdGXYSelectController which has this ILcdGXYSelectControllerModel as a property. By implementing this method, one can, for instance, display a popup menu displaying the names of the touched Objects, ask the use to pick one, and make the picked object selected on the given ILcdGXYView.

Parameters:

aPotentialSelection - the touched Object grouped by the ILcdGXYLayer that contains them.

aMouseEvent - the mouse event that triggered the selection

aGXYView - the view for which the selection is meant
