Method Detail

exportAsDrag

public void exportAsDrag(JComponent comp,
                         InputEvent e,
                         int action)

First method being called to initiate drag, usually by mouseDragged in MouseMotionListener. This method overrides TransferHandler exportAsDrag and saves drag initiating component and the drag location.

getSourceActions

public int getSourceActions(JComponent c)

Second method called after initiating drag to get supported actions

Returns:

source action supported

createTransferable

protected Transferable createTransferable(JComponent dragComponent)

Third method called during drag and drop. Creates DestkopIconTransferable object containing the selected icons on our desktop

Returns:

DesktopIconTransferable object containing selected icons on desktop

canImport

public boolean canImport(JComponent dropComponent,
                         DataFlavor[] flavors)

Returns:

true if data flavor is supported

importData

public boolean importData(JComponent c,
                          Transferable t)

Most important method during drop operation. This method is called by the drop method in DropHandler after a succesful drop. This method performs actions of moving icons if drop is on desktop, or launching if drop is on icon.

Returns:

true if import was successful

getDropHandler

public static org.globus.cog.gridface.impl.desktop.dnd.DesktopTransferHandler.DropHandler getDropHandler()

Returns:

return drop handler

getDropPoint

public Point getDropPoint()

setDropPoint

public void setDropPoint(Point dropPoint)

getDragPoint

public Point getDragPoint()

setDragPoint

public void setDragPoint(Point dragPoint)

getDragComponent

public JComponent getDragComponent()

setDragComponent

public void setDragComponent(JComponent dragComponent)

getDropComponent

public JComponent getDropComponent()

setDropComponent

public void setDropComponent(JComponent dropComponent)
