public MapSelectionLogic(MapApp app)

Method Detail

initialize

public void initialize()

Initializes the view from preferences.

getSelectedItem

public MapDataItem getSelectedItem()

getLocationNearestLastSelect

public Point getLocationNearestLastSelect()

Returns the point (the point itself for point or text items; a vertex for lines and areas and merged items) for current selection nearest the coordinates of the last mouse selection event. Perhaps simpler: the part of the selected graphic nearest where the user clicked to select it.

selectPrevious

public void selectPrevious()

Selects the previous item in the selection list. Loops if already on the first item.

selectNext

public void selectNext()

Selects the next item in the selection list. Loops if already on the last item.

addToSelectionList

public void addToSelectionList(java.util.ArrayList smore)

Adds the contents of a list to the existing contents of the selection list.

setSelectionList

public void setSelectionList(java.util.ArrayList newList)

setSelectionList

public void setSelectionList(java.util.ArrayList newList,
                             int newCurrentSelection)

setCurrentSelection

public void setCurrentSelection(int newSelection)
