All Implemented Interfaces:

Serializable, UIResource

Enclosing class:

JTextComponent

static class JTextComponent.DefaultTransferHandler

extends TransferHandler

implements UIResource

A Simple TransferHandler that exports the data as a String, and imports the data from the String clipboard. This is only used if the UI hasn't supplied one, which would only happen if someone hasn't subclassed Basic.

Method Detail

exportToClipboard

public void exportToClipboard(JComponent comp,
                              Clipboard clipboard,
                              int action)

Description copied from class: TransferHandler

Causes a transfer from the given component to the given clipboard. This method is called by the default cut and copy actions registered in a component's action map.

The transfer will have been completed at the return of this call. The transfer will take place using the java.awt.datatransfer mechanism, requiring no further effort from the developer. The exportDone method will be called when the transfer has completed.

Overrides:

exportToClipboard in class TransferHandler

Parameters:

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

clipboard - the clipboard to transfer the data into

action - the transfer action requested; this should be a value of either COPY or MOVE; the operation performed is the intersection of the transfer capabilities given by getSourceActions and the requested action; the intersection may result in an action of NONE if the requested action isn't supported

importData

public boolean importData(JComponent comp,
                          Transferable t)

Description copied from class: TransferHandler

Causes a transfer to a component from a clipboard or a DND drop operation. The Transferable represents the data to be imported into the component.

Overrides:

importData in class TransferHandler

Parameters:

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

t - the data to import

Returns:

true if the data was inserted into the component, false otherwise

canImport

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

Description copied from class: TransferHandler

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

getSourceActions

public int getSourceActions(JComponent c)

Description copied from class: TransferHandler

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

getFlavor

private DataFlavor getFlavor(DataFlavor[] flavors)
