Class TableReshapeHandler

java.lang.Object

com.yworks.yfiles.view.input.TableReshapeHandler

All Implemented Interfaces:

IReshapeHandler

public class TableReshapeHandler
extends Object
implements IReshapeHandler

IReshapeHandler implementation that constrains node resizes so that minimum size constraints of an associated ITable are satisfied and which resizes the outer IStripes of such a table when the node is resized.

The constraints are applied in addition to any constraints imposed by the IReshapeHandler which is wrapped by this implementation.

Constructor Summary

Constructors

Constructor and Description
TableReshapeHandler(IReshapeHandler coreHandler, INode tableNode, ITable table) Creates a new instance of this Handler which wraps an existing instance of coreHandler and uses table for additional constraints.

Constructor Detail

TableReshapeHandler

public TableReshapeHandler(IReshapeHandler coreHandler,
                           INode tableNode,
                           ITable table)

Creates a new instance of this Handler which wraps an existing instance of coreHandler and uses table for additional constraints.

In addition, table's outer stripes are resized if necessary.

table should be associated to tableNode

Parameters:

coreHandler - The handler that is wrapped by this instance.

tableNode - The node for which this handler is used

table - The table that is used for additional constraints.

Method Detail

cancelReshape

public final void cancelReshape(IInputModeContext context,
                                RectD originalBounds)

Description copied from interface: IReshapeHandler

Called by clients to indicate that the reshaping has been canceled by the user.

This method may be called after the initial IReshapeHandler.initializeReshape(IInputModeContext) and zero or more invocations of IReshapeHandler.handleReshape(IInputModeContext, RectD, RectD). Implementations should reset the bounds of the items they modify to their initial state. Alternatively to this method the IReshapeHandler.reshapeFinished(IInputModeContext, RectD, RectD) method might be called.

Specified by:

cancelReshape in interface IReshapeHandler

Parameters:

context - The context to retrieve information about the reshaping from.

originalBounds - The value of the coordinate of the Bounds property at the time of IReshapeHandler.initializeReshape(IInputModeContext).

getBounds

public final IRectangle getBounds()

Description copied from interface: IReshapeHandler

Returns a view of the bounds of the item.

The rectangle describes the current world coordinate of the element that can be modified by this handler.

Specified by:

getBounds in interface IReshapeHandler

Returns:

The Bounds.

getCoreHandler

public final IReshapeHandler getCoreHandler()

The core reshape handler wrapped by this instance.

Returns:

The CoreHandler.

getTable

public final ITable getTable()

The table used for additional constraints.

Returns:

The Table.

getTableNode

public final INode getTableNode()

The node this handler is used for.

Returns:

The TableNode.

handleReshape

public final void handleReshape(IInputModeContext context,
                                RectD originalBounds,
                                RectD newBounds)

Description copied from interface: IReshapeHandler

Called by clients to indicate that the element has been dragged and its position should be updated.

This method may be called more than once after an initial IReshapeHandler.initializeReshape(IInputModeContext) and will the final call will be followed by either one IReshapeHandler.reshapeFinished(IInputModeContext, RectD, RectD) or one IReshapeHandler.cancelReshape(IInputModeContext, RectD) call.

Specified by:

handleReshape in interface IReshapeHandler

Parameters:

context - The context to retrieve information about the reshaping from.

originalBounds - The value of the Bounds property at the time of IReshapeHandler.initializeReshape(IInputModeContext).

newBounds - The coordinates of the bounds in the world coordinate system that the client wants the shape to be at. Depending on the implementation the Bounds may or may not be modified to reflect the new value.

initializeReshape

public final void initializeReshape(IInputModeContext context)

Description copied from interface: IReshapeHandler

Called by clients to indicate that the element is going to be reshaped.

This call will be followed by one or more calls to IReshapeHandler.handleReshape(IInputModeContext, RectD, RectD), and a final IReshapeHandler.reshapeFinished(IInputModeContext, RectD, RectD) or IReshapeHandler.cancelReshape(IInputModeContext, RectD).

Specified by:

initializeReshape in interface IReshapeHandler

Parameters:

context - The context to retrieve information about the drag from.

reshapeFinished

public final void reshapeFinished(IInputModeContext context,
                                  RectD originalBounds,
                                  RectD newBounds)

Description copied from interface: IReshapeHandler

Called by clients to indicate that the reshaping has just been finished.

This method may be called after the initial IReshapeHandler.initializeReshape(IInputModeContext) and zero or more invocations of IReshapeHandler.handleReshape(IInputModeContext, RectD, RectD). Alternatively to this method the IReshapeHandler.cancelReshape(IInputModeContext, RectD) method might be called.

Specified by:

reshapeFinished in interface IReshapeHandler

Parameters:

context - The context to retrieve information about the drag from.

originalBounds - The value of the coordinate of the Bounds property at the time of IReshapeHandler.initializeReshape(IInputModeContext).

newBounds - The coordinates of the bounds in the world coordinate system that the client wants the shape to be at. Depending on the implementation the Bounds may or may not be modified to reflect the new value. This is the same value as delivered in the last invocation of IReshapeHandler.handleReshape(IInputModeContext, RectD, RectD)
