Method Detail

getAvailableHandles

public HandlePositions getAvailableHandles(IInputModeContext context)

Returns the HandlePositions property.

Specified by:

getAvailableHandles in interface IReshapeHandleProvider

Parameters:

context - The context for which the handles are queried.

Returns:

A bitwise combination of all handle positions this instance provides a handle for if queried in RectangleReshapeHandleProvider.getHandle(IInputModeContext, HandlePositions).

getHandle

public abstract IHandle getHandle(IInputModeContext context,
                                  HandlePositions position)

Provides a IHandle that uses the rectangle and reshapeable instance bound to this instance to perform the actual reshaping.

This method may be called for each possible single position contained in the set as returned by getAvailableHandles(IInputModeContext).

Specified by:

getHandle in interface IReshapeHandleProvider

Parameters:

context - The context for which the handles are queried.

position - The position to provide an instance for.

Returns:

A handle implementation.

getHandlePositions

public final HandlePositions getHandlePositions()

Gets the bitwise combination of all handle positions this instance provides a handle for.

Returns:

The HandlePositions.

getMaximumSize

public final ISize getMaximumSize()

Gets the maximum size allowed for the reshapeable.

The default value is SizeD.INFINITE.

Returns:

The maximum size.

See Also:

RectangleHandle.getMaximumSize(), setMaximumSize(ISize)

getMinimumEnclosedArea

public final IRectangle getMinimumEnclosedArea()

Gets the minimum rectangular area that needs to be contained in the reshapeable.

The default value is SizeD.ZERO.

Returns:

The minimum size.

See Also:

RectangleHandle.getMinimumEnclosedArea(), setMinimumEnclosedArea(IRectangle)

getMinimumSize

public final ISize getMinimumSize()

Gets the minimum size allowed for the reshapeable.

The default value is SizeD.ZERO.

Returns:

The minimum size.

setHandlePositions

public final void setHandlePositions(HandlePositions value)

Sets the bitwise combination of all handle positions this instance provides a handle for.

Parameters:

value - The HandlePositions to set.

setMinimumEnclosedArea

public final void setMinimumEnclosedArea(IRectangle value)

Sets the minimum rectangular area that needs to be contained in the reshapeable.

The default value is SizeD.ZERO.

Parameters:

value - The minimum size.

See Also:

RectangleHandle.getMinimumEnclosedArea(), getMinimumEnclosedArea()

setMinimumSize

public final void setMinimumSize(ISize value)

Sets the minimum size allowed for the reshapeable.

The default value is SizeD.ZERO.

Parameters:

value - The minimum size.
