XtGetSelectionValueIncremental
NAME
XtGetSelectionValueIncremental, XtGetSelectionValuesIncremental - obtain selection values
SYNTAX
void XtGetSelectionValueIncremental(Widget w, Atom selection, Atom
target, XtSelectionCallbackProc callback, XtPointer
client_data, Time time);
void XtGetSelectionValuesIncremental(Widget w, Atom selection,
Atom *targets, int count, XtSelectionCallbackProc callback,
XtPointer client_data, Time time);
ARGUMENTS
callback
Specifies the callback procedure.
client_data
Specifies the argument that is to be passed to the specified procedure
when .
client_data
Specifies the client data (one for each target type)
that is passed to the callback procedure when it is called for that target.
count
Specifies the length of the targets and client_data lists.
selection
Specifies the particular selection desired (that is, primary or secondary).
target
Specifies the type of the information that is needed about the selection.
targets
Specifies the types of information that is needed about the selection.
time
Specifies the timestamp that indicates when the selection .
w
Specifies the widget .
DESCRIPTION
The
function is similar to
except that the selection_callback procedure will be called
repeatedly upon delivery of multiple segments of the selection value.
The end of the selection value is indicated when selection_callback
is called with a non-NULL value of length zero, which must still be
freed by the client. If the transfer of the selection is aborted in the
middle of a transfer (for example, because to timeout), the
selection_callback procedure is called with a type value equal
to the symbolic constant
so that the requestor can dispose of the partial selection value it has
collected up until that point. Upon receiving
the requesting client must determine for itself whether or not a
partially completed transfer is meaningful.
The
function is similar to
except that it takes a list of target types and a list of client data
and obtains the current value of the selection converted to each of the targets.
The effect is as if each target were specified in a separate call to
The callback is called once with the corresponding client data for each target.
does guarantee that all the conversions will use the same selection value
because the ownership of the selection cannot change in the middle of the list,
as would be when calling
repeatedly.
