IInputMode
```
public class GraphEditorInputMode
extends MultiplexingInputMode
```
A complex IInputMode that can be used in a GraphControl to edit an IGraph instance.
This class delegates most of the work to minor IInputMode implementations. However it contains a number of properties that influence the general behavior:
- SelectableItems – Determines the types of items that can be selected at all.
- SelectablePredicate – Allows to further constrain SelectableItems with a predicate.
- MarqueeSelectableItems – Determines the types of items that can be selected with marquee selection.
- ClickSelectableItems – Determines the types of items that can be selected by clicking them.
- DetailSelectionRecognizer – Determines when to use a detail click selection mode, which allows for selecting the item that is directly under the mouse without taking into account the ClickHitTestOrder.
- ClickHitTestOrder – Determines the priorities for hit tests during mouse clicks to determine which items should get click events.
- DoubleClickHitTestOrder – Determines the priorities for hit tests when double-clicking items.
- MovableItems – Determines the type of the items that can be moved with the mouse.
- ShowHandleItems – Determines the type of the items whose IHandles should be shown and movable by the HandleInputMode.
- DeletableItems – Determines the type of the items that can be deleted by deleteSelection().
- DeletablePredicate – Allows to further constrain DeletableItems with a predicate.
- LabelEditableItems – Determines the type of the items that can have their labels edited.
- GroupingOperationsAllowed – Determines whether this input mode should allow grouping operations at all.
- GroupSelectionAllowed – Determines whether this input mode should allow grouping the current selection.
- UngroupSelectionAllowed – Determines whether this input mode should allow ungrouping the current selection.
- ClearSelectionAllowed – Determines whether this input mode should allow clearing the selection. This has implications both for the ICommand.DESELECT_ALL and for click/marquee selection which usually clear the selection unless the MultiSelectionRecognizer is pressed.
- ClipboardOperationsAllowed – Determines whether this input mode should enable graph clipboard operations.
- DuplicateAllowed – Determines whether this input mode should enable graph clipboard's GraphClipboard.duplicate(IInputModeContext, IGraph, Predicate, com.yworks.yfiles.graph.IElementCopiedCallback) operation.
- EditLabelAllowed – Determines whether this input mode should allow editing labels.
- ReparentNodesAllowed – Determines whether this input mode should allow reparenting nodes to other groups.
- CreateNodeAllowed – Determines whether this input mode should allow creating new nodes via simple mouse clicks.
- CreateEdgeAllowed – Determines whether CreateEdgeInputMode should be Enabled to allow for creating new edges.
- EditLabelOnDoubleClickAllowed – Determines whether labels should be editable on otherwise unhandled double clicks.
- ReverseEdgeAllowed – Determines whether edges can be reversed.
- CreateBendAllowed – Determines whether the CreateBendInputMode should be Enabled to allow for creating new bends.
- EnterGroupAllowed – Determines whether the mode allows for entering group nodes in IFoldingViews.
- ExitGroupAllowed – Determines whether the mode allows for exiting the current group node in IFoldingViews.
- CollapseGroupAllowed – Determines whether the mode allows for collapsing group nodes in IFoldingViews.
- ExpandGroupAllowed – Determines whether the mode allows for expanding group nodes in IFoldingViews.
- HoverItems – Determines which items should be reported as being hovered through the corresponding event in this instance's ItemHoverInputMode.
- GraphInputMode.shouldInstallCommand(ICommand) – Determines which of the built-in ICommands this input mode should provide and install.
By default, GraphEditorInputMode supports the following commands. Most of them have default keybindings:
- ICommand.UNDO (Ctrl+Z on Windows and Linux and Command+Z on Mac OS) – Undoes the last operation. Can be disabled with UndoOperationsAllowed.
- ICommand.REDO (Ctrl+Y on Windows and Linux and Command+Y on Mac OS)) – Redoes the last operation that was undone. Can be disabled with UndoOperationsAllowed.
- ICommand.SELECT_ALL (Ctrl+A on Windows and Linux and Command+A on Mac OS)) – Selects all items. Can be configured with SelectableItems and SelectablePredicate.
- ICommand.DESELECT_ALL (Ctrl+Shift+A on Windows and Linux and Command+Shift+A on Mac OS)) – Clears the current selection. Can be disabled with ClearSelectionAllowed.
- ICommand.CUT (Ctrl+X, Shift+Del on Windows and Linux and Command+Del on Mac OS)) – Cuts the current selection and places it in the clipboard. Can be disabled with ClipboardOperationsAllowed.
- ICommand.COPY (Ctrl+C, Ctrl+Ins on Windows and Linux and Command+C, Command+Ins on Mac OS)) – Copies the current selection to the clipboard. Can be disabled with ClipboardOperationsAllowed.
- ICommand.PASTE (Ctrl+V, Shift+Ins on Windows and Linux and Command+V, Shift+Ins on Mac OS)) – Pastes the current clipboard contents into the graph. Can be disabled with ClipboardOperationsAllowed.
- ICommand.DUPLICATE (Ctrl+D on Windows and Linux and Command+D on Mac OS)) – Duplicates the current selection. Can be disabled with DuplicateAllowed.
- ICommand.DELETE (Del) – Deletes the current selection. Can be configured with DeletablePredicate and DeletableItems.
- ICommand.ADD_LABEL (Shift+F2) – Adds a new label to the selected item. Can be configured with LabelEditableItems and disabled with AddLabelAllowed.
- ICommand.EDIT_LABEL (F2) – Edits an existing label or adds a new one to the selected item. Can be configured with LabelEditableItems and disabled with EditLabelAllowed.
- ICommand.REVERSE_EDGE (Ctrl+R on Windows and Linux and Command+R on Mac OS)) – Reverses the direction of the selected edges. Can be disabled with ReverseEdgeAllowed.
- ICommand.GROUP_SELECTION (Ctrl+G on Windows and Linux and Command+G on Mac OS)) – Creates a new group node and places the currently selected nodes into it. Can be disabled with GroupingOperationsAllowed and GroupSelectionAllowed.
- ICommand.UNGROUP_SELECTION (Ctrl+U on Windows and Linux and Command+U on Mac OS)) – Creates a new group node and places the currently selected nodes into it. Can be disabled with GroupingOperationsAllowed and UngroupSelectionAllowed.
- ICommand.ADJUST_GROUP_NODE_SIZE (Ctrl+Shift+G on Windows and Linux and Command+Shift+G on Mac OS)) – Adjusts the sizes of the selected group nodes to fit exactly around their contents. Can be disabled with GroupingOperationsAllowed and AdjustGroupNodeSizeAllowed.
All commands can also be selectively disabled by using the AvailableCommands collection. Furthermore, there are a few commands provided by NavigationInputMode:
- ICommand.COLLAPSE_GROUP (Ctrl+Minus on Windows and Linux and Command+Minus on Mac OS)) – Collapses the currently selected group nodes. Can be disabled with CollapseGroupAllowed of NavigationInputMode.
- ICommand.EXPAND_GROUP (Ctrl+Plus on Windows and Linux and Command+Plus on Mac OS)) – Expands the currently selected group nodes. Can be disabled with ExpandGroupAllowed of NavigationInputMode.
- ICommand.TOGGLE_EXPANSION_STATE (Ctrl+Multiply on Windows and Linux and Command+Multiply on Mac OS)) – Collapses expanded group nodes and expands collapsed group nodes in the current selection. Can be disabled with CollapseGroupAllowed and ExpandGroupAllowed of NavigationInputMode.
- ICommand.ENTER_GROUP (Ctrl+Enter on Windows and Linux and Command+Enter on Mac OS)) – Replaces the currently displayed graph with the contents of the selected group node. Can be disabled with EnterGroupAllowed of NavigationInputMode.
- ICommand.EXIT_GROUP (Ctrl+Backspace on Windows and Linux and Command+Backspace on Mac OS)) – Replaces the currently displayed graph with the contents of the parent of the group node whose contents are currently displayed. Can be disabled with ExitGroupAllowed of NavigationInputMode.
GraphEditorInputMode can be configured to automatically adjust the content rectangle of the GraphControl whenever the graph is changed using gestures.
This class contains a number of public methods that can be used to programmatically perform the corresponding actions, too.
Setting the NodeCreator to another instance or null changes the way nodes are created. Also the various minor IInputMode instances can be disabled, to change the behavior, too.

This input mode manages a set of specialized input modes, each handling a specific part of the interaction with the graph. The following list details those along with their default priorities. Lower priorities come earlier when handling events.
- WaitInputMode (−1) – Disables this input mode when layouts or animations run.
- HandleInputMode (0) – Deals with displaying handles on or around items and interacting with them.
- KeyboardInputMode (0) – Handles commands and arbitrary keyboard shortcuts.
- ClickInputMode (10) – Handles mouse clicks and double-clicks.
- TapInputMode (20) – Handles taps and double-tap.
- MoveViewportInputMode (39) – Allows panning the viewport.
- MoveLabelInputMode (39) – Allows moving labels to new positions.
- MoveInputMode (40) – Allows moving items that are not labels.
- CreateBendInputMode (42) – Allows creating bends on edges.
- CreateEdgeInputMode (45) – Allows creating edges
- MarqueeSelectionInputMode (50) – Allows dragging a rectangle to select items within it.
- ItemHoverInputMode (55) – Provides events to indicate that the mouse pointer hovers over an item.
- NavigationInputMode (55) – Provides general navigation facilities, such as navigating from one item to another with the arrow keys, collapsing, expanding, entering or exiting groups, as well as providing commands for those tasks.
- AbstractContextMenuInputMode (60) – Handles querying the context menu contents based on a location as well as preparing the menu for display.
- NodeDropInputMode (70) – Allows dropping nodes on the GraphControl, e.g. for dragging items from a palette.
- MouseHoverInputMode (100) – Handles tool tips.
- TextEditorInputMode (100) – Handles editing labels.
To enable single selection mode, disable MarqueeSelectionInputMode and set MultiSelectionRecognizer to IEventRecognizer.NEVER. Remove ICommand.SELECT_ALL and ICommand.TOGGLE_ITEM_SELECTION from AvailableCommands and from NavigationInputMode.AvailableCommands. An example can be found in Demo.yFiles.Graph.Input.SingleSelection.

An overview of this input mode is given in the section Editing Graphs. Additionally, specific support for graph hierarchies is discussed in Supported User Interactions: Grouping.

- Constructor Detail
  - GraphEditorInputMode
```
public GraphEditorInputMode()
```
    Creates a new instance that is not bound to an existing graph or selection, initially.
    The IGraph and IGraphSelection instances are obtained later from the IInputModeContext once this mode gets installed in a suitable canvas control.
- Method Detail
  - addDeletedItemListener
```
public final void addDeletedItemListener(IEventHandler<ItemEventArgs<IModelItem>> deletedItemEvent)
```
    Adds the given listener for the DeletedItem event that occurs when an item has been deleted interactively by this mode.
    Note that this event will not be triggered for items that are removed implicitly, e.g. if the event is triggered for a node, its labels, ports, and adjacent edges will not necessarily be reported separately. In order to be notified of any removal events, the IGraph events should be used instead.
    
    Parameters:
    
    deletedItemEvent - The listener to add.
    
    See Also:
    
    removeDeletedItemListener(IEventHandler)
  - addDeletedSelectionListener
```
public final void addDeletedSelectionListener(IEventHandler<SelectionEventArgs<IModelItem>> deletedSelectionEvent)
```
    Adds the given listener for the DeletedSelection event that occurs just before the deleteSelection() method has deleted the selection after all selected items have been removed.
    
    Parameters:
    
    deletedSelectionEvent - The listener to add.
    
    See Also:
    
    deleteSelection(), removeDeletedSelectionListener(IEventHandler)
  - addDeletingSelectionListener
```
public final void addDeletingSelectionListener(IEventHandler<SelectionEventArgs<IModelItem>> deletingSelectionEvent)
```
    Adds the given listener for the DeletingSelection event that occurs just before the deleteSelection() method starts its work and will be followed by any number of DeletedItem events and finalized by a DeletedSelection event.
    
    Parameters:
    
    deletingSelectionEvent - The listener to add.
    
    See Also:
    
    deleteSelection(), removeDeletingSelectionListener(IEventHandler)
  - addEdgePortsChangedListener
```
public final void addEdgePortsChangedListener(IEventHandler<EdgeEventArgs> edgePortsChangedEvent)
```
    Adds the given listener for the EdgePortsChanged event that occurs after an edge's source and/or target ports have been changed as the result of an input gesture.
    
    Parameters:
    
    edgePortsChangedEvent - The listener to add.
    
    See Also:
    
    EdgeEventArgs, reverseSelectedEdges(), reverseEdges(Iterable), reverseEdge(IEdge), removeEdgePortsChangedListener(IEventHandler)
  - addLabel
```
public Future<ILabel> addLabel(ILabelOwner owner)
```
    Adds a new label to the given item interactively.
    This will activate the TextEditorInputMode to let the user interactively enter the label's text and unless the user cancels label creation the returned Future will contain the label.
    
    The text that the user enters may be validated before the label is actually added.
    
    This method works nearly identical to createLabel(ILabelOwner). The only difference is when either the LabelAdding event is handled, or owner has an IEditLabelHelper, and via those instead of adding a label an existing one should be edited. This method will edit that label instead of adding a new one.
    
    Parameters:
    
    owner - The item to add a label to.
    
    Returns:
    
    A future of the label that will be notified of the newly created label or a null if the creation was canceled.
  - addLabelAddedListener
```
public final void addLabelAddedListener(IEventHandler<LabelEventArgs> labelAddedEvent)
```
    Adds the given listener for the LabelAdded event that occurs when this mode has triggered the addition of an ILabel, for instance, in response to createLabel(ILabelOwner).
    
    Parameters:
    
    labelAddedEvent - The listener to add.
    
    See Also:
    
    removeLabelAddedListener(IEventHandler)
  - addLabelAddingListener
```
public final void addLabelAddingListener(IEventHandler<LabelEditingEventArgs> labelAddingEvent)
```
    Adds the given listener for the LabelAdding event that occurs when a label is about to be added.
    Event handlers for this event can customize the behavior for adding a new label extensively. Adding a label can be forbidden entirely, or the properties of the added label can be changed, by setting the appropriate properties on the LabelEditingEventArgs. It is even possible to forbid adding a label, but edit an existing one instead.
    
    Parameters:
    
    labelAddingEvent - The listener to add.
    
    See Also:
    
    removeLabelAddingListener(IEventHandler)
  - addLabelEditingListener
```
public final void addLabelEditingListener(IEventHandler<LabelEditingEventArgs> labelEditingEvent)
```
    Adds the given listener for the LabelEditing event that occurs when a label is about to be edited.
    Event handlers for this event can customize the behavior for editing an existing label. Editing can be forbidden entirely, or redirected to a different label, even on a different owner. In case editing existing labels is unwanted, event handlers can also specify that instead of editing a label, a new one should be added.
    
    Parameters:

  - editLabel
```
public void editLabel(ILabel label)
```
    Starts editing the given label.
    This implementation uses the TextEditorInputMode to display an editor to edit the label. The text that the user enters may be validated before the label is actually edited.
    
    The label to edit can be a SimpleLabel, which will be edited as usual, except that the label text changes will be written directly back into the instance.
    
    This method will raise the LabelEditing event and query the IEditLabelHelper for the label and its owner, but will ignore the result except for the TextEditorInputModeConfigurator property on the LabelEditingEventArgs. Thus editing a label via this method cannot be prevented by event handlers or IEditLabelHelpers.
    
    Parameters:
    
    label - The label to edit.
    
    See Also:
    
    onLabelTextEdited(ILabel, String)

    This method differs from a simple call to IGraph.setNodeLayout(INode, RectD) in a number of ways:
    - An undo unit is enqueued.
    - The node is reshaped interactively using the IReshapeHandler implementation found in its lookup. This enables correctly adjusting e.g. affected orthogonal edges and parent group nodes.
    - adjustContentRect() is called.

    If the recognizer determines that the user wanted to use the cyclic click selection behavior, the HitTester will be queried for the given item and previously reported items will be ignored. E.g. if multiple nodes are overlapping each other, clicking on them will report the first item for the first click, the second one for the second click and so on. If all elements have been reported previously, the first one is going to be reported again. If the order of the elements at the clicked location changes, the cyclic selection is restarted anew.

  - setCyclicSelectionRecognizer
```
public final void setCyclicSelectionRecognizer(IEventRecognizer value)
```
    Sets the IEventRecognizer that will be queried to decide if a click should cycle through all the items that are currently under the mouse cursor.
    If the recognizer determines that the user wanted to use the cyclic click selection behavior, the HitTester will be queried for the given item and previously reported items will be ignored. E.g. if multiple nodes are overlapping each other, clicking on them will report the first item for the first click, the second one for the second click and so on. If all elements have been reported previously, the first one is going to be reported again. If the order of the elements at the clicked location changes, the cyclic selection is restarted anew.
    
    The default is IEventRecognizer.ALT_PRESSED.
    
    Parameters:

```
    Sets the IEventRecognizer that will be queried to decide if a click should select the item that is currently visible under the mouse cursor, without giving more important items higher priority.
    If the recognizer determines that the user wanted to use the detail clicking behavior, the HitTester will be queried for the given item and the first item that is returned will be considered a hit. Otherwise all hit items are examined and are prioritized by item type. E.g. by default clicking on a node will select the node, even if there is a node label which has been clicked at the same point. If detail selection is recognized, the label will be selected.
    
    The default is IEventRecognizer.SHIFT_PRESSED.

  - shouldSelectItem
```
protected boolean shouldSelectItem(IModelItem item)
```
    Callback predicate method that is used as a broad classification whether an item can generally be selected.
    This implementation uses and honors the SelectableItems, IgnoringVoidStylesEnabled and SelectablePredicate properties. This method is by default also called by shouldClickSelect(IModelItem) and shouldMarqueeSelect(IModelItem), so turning selection off here also turns it off in other places.
    
    Parameters:
    
    item - The item to check.
    
    Returns:
    
    true if the item is selectable in general, false if not.
  - tap
```
protected void tap(IModelItem item,
                   TapEventArgs args)
```
    Actually performs the tap on the given item.
    This will raise the ItemClicked event. If the event is unhandled by all its event handlers the item will be selected and focused. Before selection the current selection will be cleared.
    
    Parameters:
    
    item - The item that has been tapped.
    
    args - The original event arguments for the tap. Setting its Handled property to true will indicate that the tap was handled. By default this happens when the tapped item is either selected or focused.
