Usage

From source file:org.fife.ui.rtextarea.RTATextTransferHandler.java

/**
 * This method 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.  /* ww  w  .j  av a2s  . co  m*/
 *
 * @param comp  The component to receive the transfer.  This
 *  argument is provided to enable sharing of TransferHandlers by
 *  multiple components.
 * @param t The data to import
 * @return <code>true</code> iff the data was inserted into the component.
