Class SelectionManager

java.lang.Object
  apollo.gui.SelectionManager

All Implemented Interfaces:

ControlledObjectI, java.io.Serializable

public class SelectionManager
extends java.lang.Object
implements ControlledObjectI

Controller for selection. This is only partially implemented at this point. The idea would be that this would be the controller for selection, replacing Controller for just selection (not everything else it controls. SelectionManager deals with selection and deselection where Controller only passes along selects and does not deal with deselecting when new selects come in. When SelectionManager gets a new select it does the appropriate deselecting to accompnay this. note from cvs notes that i thought would be clariflying to put here: Fixed slowness of selection in the views. When i changed selection to be model based the views were just sending out the model selected and then receiving that model and having to refind the associated view which was obviously inefficient. I managed to solve this issue and keep selection model based (rather than having drawables as the data in the SelectionItems) by attaching the drawables as selectionListeners to the SelectionItems which hold the model(SeqFeatureI) of the drawable. So the SelectionItems are told to select and deselect (by the SelectionManager via Selection) and the SelectionItems tell their drawable selection listeners to select and deselect, thus avoiding having to refind them at handleFeatureSelectionEvent. At the moment only the ApolloPanel(and its views) participate in putting selectionListeners on the SelectionItems, but clearly any other selection source could do the same, but they probably dont need to since they dont have the intense selection needs that ApolloPanel has. ApolloPanel.handleFeatureSelectionEvent doesnt search for drawables if the event source is itself. Im thinking this should be in a apollo.controller package.

SelectionManager

public SelectionManager()

Method Detail

select

public void select(FeatureList feats,
                   boolean exclusiveSelection,
                   boolean selectParents,
                   java.lang.Object source)

select

public void select(Selection newSelection,
                   boolean exclusiveSelection,
                   java.lang.Object source)

Process selection of Selection

Parameters:

newSelection - Selection to add to or replace old selection

exclusiveSelection - whether to add or replace old selection

source - source(view) of the selection, gets put in sel event

select

public void select(SeqFeatureI feat,
                   java.lang.Object source)

select

public void select(java.util.Vector features,
                   java.lang.Object source)

addToCurrentSelection

public void addToCurrentSelection(Selection newSelection)

Just adds newSelection to the current selection. Similar to doing a non exclusive select except there is no firing of a selection event. This is handy for SiteView slipping in a codon from transcript selection, no need to trigger another selection event(which can get sluggish with large selections. (An alternate approach we may want to consider is only firing new stuff on non-exclusive selection, possible now with exclusivity in selection event)

getSelection

public Selection getSelection()

clearSelections

public void clearSelections()

clear() is called on the currently selected Selection. Selection calls deselect on all of its SelectionItems. SelectionItem calls setSelected(false) on all of its selection listeners, and the drawable is a selection listener. This is how drawables get deselected

setController

public void setController(Controller c)

Part of ControlledObjectI interface

Specified by:

setController in interface ControlledObjectI

getController

public Controller getController()

Part of ControlledObjectI interface

Specified by:

getController in interface ControlledObjectI

getControllerWindow

public java.lang.Object getControllerWindow()

Part of ControlledObjectI interface. If we've been set up with an ApolloPanel, use it to find the ControllerWindow. Otherwise return null.

Specified by:

getControllerWindow in interface ControlledObjectI

needsAutoRemoval

public boolean needsAutoRemoval()

Part of ControlledObjectI interface

Specified by:

needsAutoRemoval in interface ControlledObjectI
