BookmarkTransferHandler

public BookmarkTransferHandler()

Method Detail

createTransferable

public Transferable createTransferable(JComponent c)

Creates a Transferable to use as the source for a data transfer. Returns the representation of the data to be transferred, or null if the component's property is null

Overrides:

createTransferable in class TransferHandler

Parameters:

c - the component holding the data to be transferred; this argument is provided to enable sharing of TransferHandlers by multiple components

Returns:

the representation of the data to be transferred, or null if the property associated with c is null

canImport

public boolean canImport(JComponent comp,
                         DataFlavor[] transferFlavors)

Indicates whether a component would accept an import of the given set of data flavors prior to actually attempting to import it.

Overrides:

canImport in class TransferHandler

Parameters:

comp - the component to receive the transfer; this argument is provided to enable sharing of TransferHandlers by multiple components

transferFlavors - the data formats available

Returns:

true if the data can be inserted into the component, false otherwise

Todo:

correctly implement this

getSourceActions

public int getSourceActions(JComponent c)

Returns the type of transfer actions supported by the source. Some models are not mutable, so a transfer operation of COPY only should be advertised in that case.

Overrides:

getSourceActions in class TransferHandler

Parameters:

c - the component holding the data to be transferred; this argument is provided to enable sharing of TransferHandlers by multiple components.

Returns:

COPY if the transfer property can be found, otherwise returns NONE; a return value of of NONE disables any transfers out of the component
