XtSelDoneIn(3x) — HPUX 9.05

NAME

XtSelectionDoneIncrProc − interface definition for procedure called when an incremental selection transfer completes.

Synopsis

typedef void (*XtSelectionDoneIncrProc)(Widget, Atom *, Atom *,
XtRequestId *, XtPointer);

    Widget w;
    Atom *selection;
    Atom *target;
    XtRequestId *request_id;
    XtPointer client_data;

Inputs

wSpecifies the widget that owns the selection.

selectionSpecifies the atom that names the selection being transferred.

targetSpecifies the target type to which the conversion was done.

request_id
Identifies the specific conversion request that completed.

client_data
Specifies data registered with this procedure when the widget took ownership of the selection.

Availability

Release 4 and later.

Description

An XtSelectionDoneIncrProc is optionally registered in a call to XtOwnSelectionIncremental(), and is called by the Intrinsics after the requestor has retrieved the final (zero-length) segment of the incremental transfer to indicate that the entire transfer is complete. The w, selection, and client_data arguments are those passed to XtOwnSelectionIncremental(). The target and request_id arguments are those that were passed to the XtConvertSelectionIncrProc registered with this procedure. An XtSelectionDoneIncrProc should free any memory that was allocated for the transfer of the selection value. If no procedure is specified, the Intrinsics will automatically free (using XtFree()) the last value returned by the XtConvertSelectionIncrProc. If a single buffer is used to transfer all the chunks of the selection, this automatic freeing by the Intrinsics should be sufficient. If separate buffers are used or other memory or resources are allocated to transfer the selection value, an XtSelectionDoneIncrProc should be provided to free them.

Usage

It is usually more convenient to use the Intrinsics atomic selection transfer mechanism which transfers the selection value in a single chunk. See XtOwnSelection(1) and XtSelectionDoneProc for more information.
