xmtransferdone
XmTransferDone(library call) XmTransferDone(library call) NAME
XmTransferDone -- A toolkit function that completes a data transfer SYNOPSIS
#include <Xm/Xm.h> void XmTransferDone( XtPointer transfer_id, XmTransferStatus status); DESCRIPTION
XmTransferDone completes an already-initiated data transfer operation. An application can call this routine from an XmNdestinationCallback procedure or any function called as a result, including the selection procedures called as a result of calls to XmTransferValue. The caller of XmTransferDone supplies an identifier for the transfer operation and an indication of the completion status. XmTransferDone causes any remaining transfers for the operation to be discarded. transfer_id Specifies a unique indentifier for the data transfer operation. The value must be the same as the value of the transfer_id mem- ber of the XmDestinationCallbackStruct passed to the XmNdestinationCallback procedure. status Specifies the completion status of the data transfer. Following are the possible values: XmTRANSFER_DONE_SUCCEED The transfer was completed successfully. This status has the following additional effects: o For a move operation, the selection owner receives a request to convert the selection to the DELETE target. o If a TRANSACT operation is in progress, the owner receives a request to commit the transaction. o If a PERSIST or _MOTIF_SNAPSHOT operation is in progress, the owner receives a notification that the operation is finished. o The widget class destination procedure is not called. XmTRANSFER_DONE_FAIL The transfer was completed unsuccessfully. This status has the following additional effects: o For a move operation, the selection owner does not receive a request to convert the selection to the DELETE tar- get. o For a drag and drop operation, the DropTransfer's XmNtransferStatus is set to XmTRANSFER_FAILURE. o If a TRANSACT operation is in progress, the owner receives a request to abort the transaction. o If a PERSIST or _MOTIF_SNAPSHOT operation is in progress, the owner receives a notification that the operation is finished. o The widget class destination procedure is not called. XmTRANSFER_DONE_CONTINUE This status has the same effect as XmTRANSFER_DONE_SUCCEED, except that if a PERSIST or _MOTIF_SNAPSHOT operation is in progress, the owner does not receive a notification that the operation is finished. XmTRANSFER_DONE_DEFAULT The widget class destination procedure is called. Further effects depend on the actions of that procedure. RELATED
