NAME

7       Request - bundle multiple selection conversion requests into a single
8       request using MULTIPLE target

SYNTAX

11       #include <X11/Intrinsic.h>
12
13       void XtCreateSelectionRequest(Widget requestor, Atom selection);
14
15       void XtSendSelectionRequest(Widget requestor, Atom selection, Time
16              time);
17
18       void XtCancelSelectionRequest(Widget requestor, Atom selection);
19

ARGUMENTS

21       requestor Specifies the widget making the request.  Must be of class
22                 Core or a subclass thereof.
23
24       selection Specifies the particular selection desired.
25
26       time      Specifies the timestamp to be used in making the request.

DESCRIPTION

29       When XtCreateSelectionRequest is called, subsequent calls to XtGetSe‐
30       lectionValue and XtGetSelectionValueIncremental with the requestor and
31       selection as specified to XtCreateSelectionRequest will be bundled into
32       a single selection conversion request with multiple targets.  The
33       request is actually initiated by calling XtSendSelectionRequest.
34
35       When XtSendSelectionRequest is called with a value of requestor and
36       selection matching a previous call to XtCreateSelectionRequest, a
37       selection conversion request is actually sent to the selection owner.
38       If a single target request is queued, that request is made.  If multi‐
39       ple targets are queued they are bundled into a single request with the
40       target MULTIPLE using the specified timestamp.  As the conversions are
41       made, the callbacks associated with each XtGetSelectionValue and XtGet‐
42       SelectionValueIncremental are invoked in turn.
43
44       Multi-threaded applications should lock the application context before
45       calling XtCreateSelectionRequest and release the lock after calling
46       XtSendSelectionRequest to ensure that the thread assembling the request
47       is safe from interference by another thread assembling a different
48       request naming the same widget and selection.
49
50       When XtCancelSelectionRequest is called, any requests queued since the
51       last call to XtCreateSelectionRequest are cleaned up.  Subsequent calls
52       to XtGetSelectionValue, XtGetSelectionValues, XtGetSelectionValueIncre‐
53       mental, and XtGetSelectionValuesIncremental will not be deferred.
