XtGetSelectionValueIncremental(3) XT FUNCTIONS XtGetSelectionValueIncremental(3) NAME XtGetSelectionValueIncremental, XtGetSelectionValuesIncremental - obtain selection values SYNTAX #include <X11/Intrinsic.h> void XtGetSelectionValueIncremental(Widget w, Atom selection, Atom target, XtSelectionCallbackProc callback, XtPointer client_data, Time time); void XtGetSelectionValuesIncremental(Widget w, Atom selection, Atom *tar- gets, int count, XtSelectionCallbackProc callback, XtPointer *client_data, Time time); ARGUMENTS callback Specifies the callback procedure that is to be called when the selection value has been obtained. client_data Specifies the argument that is to be passed to the specified pro- cedure when it is called. client_data Specifies the client data (one for each target type) that is passed to the callback procedure when it is called for that tar- get. 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 se- lection. time Specifies the timestamp that indicates when the selection value is desired. w Specifies the widget that is making the request. DESCRIPTION The XtGetSelectionValueIncremental function is similar to XtGetSelectionVa- lue 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 exam- ple, because to timeout), the selection_callback procedure is called with a type value equal to the symbolic constant XT_CONVERT_FAIL so that the re- questor can dispose of the partial selection value it has collected up un- til that point. Upon receiving XT_CONVERT_FAIL, the requesting client must determine for itself whether or not a partially completed transfer is mean- ingful. The XtGetSelectionValuesIncremental function is similar to XtGetSelection- ValueIncremental 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 XtGetSelectionValueIncremental. The callback is called once with the corresponding client data for each target. XtGetSelection- ValuesIncremental 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 XtGetSelectionValueIncremental repeatedly.
