public class DropSlot

extends JPanel

implements View, AppearanceConstants

A DropSlot is a simple view of a DnD-enabled model that contains one single operand. For this important subset of DnD-enabled objects, the DnDSourceContainer and DnDTargetContainer Facets of such an object can simply return the operand directly without having to know where the end-user is gesturing. In such cases, the programmer need not interact directly with the DragSourceAdapter and DropTargetAdapter functionality, and can deal with the higher-level functionality described here.

A DropSlot is suitable for use as a view component for simple "property editing" functions. The programmer supplies a model for a DropSlot, and the DropSlot uses the DnDSourceContainer and DnDTargetContainer Facets of this model for all operations. Note that this model could be a "real" model object from the application domain, or a "made-up" object serving merely to anchor the semantics of the visual operation of the DropSlot.

Method Detail

isModelSettable

public boolean isModelSettable(Object model)

Description copied from interface: View

Check if the given value is an allowable argument to View.setModel(Object). This should be overridden to provide end-user feedback regarding the correctness of a candidate model for this View, where such information is available to the implementation.

The default behavior of this method is to return true, and throw an exception in View.setModel(Object) if necessary.

Specified by:

isModelSettable in interface View

Following copied from interface: org.favabeans.base.View

Parameters:

model - the candidate model.

Returns:

false if the candidate model is known to be unacceptable; true otherwise.

setModel

public void setModel(Object model)
              throws PropertyValueException

Description copied from interface: View

Set the model of this View to a new value.

Specified by:

setModel in interface View

Following copied from interface: org.favabeans.base.View

Parameters:

model - the new model.

Throws:

PropertyValueException - if the supplied model was not acceptable.

getModel

public Object getModel()

Description copied from interface: View

Obtain the current model of this View.

Specified by:

getModel in interface View

Following copied from interface: org.favabeans.base.View

Returns:

the current model.
