15 int XConvertSelection(Display *display, Atom selection, Atom target,
16 Atom property, Window requestor, Time time);
17
19 display Specifies the connection to the X server.
20
21 owner Specifies the owner of the specified selection atom. You can
22 pass a window or None.
23
24 property Specifies the property name. You also can pass None.
25
26 requestor Specifies the requestor.
27
28 selection Specifies the selection atom.
29
30 target Specifies the target atom.
31
32 time Specifies the time. You can pass either a timestamp or Cur‐
33 rentTime.
34
36 The XSetSelectionOwner function changes the owner and last-change time
37 for the specified selection and has no effect if the specified time is
38 earlier than the current last-change time of the specified selection or
39 is later than the current X server time. Otherwise, the last-change
40 time is set to the specified time, with CurrentTime replaced by the
41 current server time. If the owner window is specified as None, then
42 the owner of the selection becomes None (that is, no owner). Other‐
43 wise, the owner of the selection becomes the client executing the
44 request.
45
46 If the new owner (whether a client or None) is not the same as the cur‐
47 rent owner of the selection and the current owner is not None, the cur‐
48 rent owner is sent a SelectionClear event. If the client that is the
49 owner of a selection is later terminated (that is, its connection is
50 closed) or if the owner window it has specified in the request is later
51 destroyed, the owner of the selection automatically reverts to None,
52 but the last-change time is not affected. The selection atom is unin‐
53 terpreted by the X server. XGetSelectionOwner returns the owner win‐
54 dow, which is reported in SelectionRequest and SelectionClear events.
55 Selections are global to the X server.
56
57 XSetSelectionOwner can generate BadAtom and BadWindow errors.
58
59 The XGetSelectionOwner function returns the window ID associated with
60 the window that currently owns the specified selection. If no selec‐
61 tion was specified, the function returns the constant None. If None is
62 returned, there is no owner for the selection.
63
64 XGetSelectionOwner can generate a BadAtom error.
65
66 XConvertSelection requests that the specified selection be converted to
67 the specified target type:
68
69 · If the specified selection has an owner, the X server sends a
70 SelectionRequest event to that owner.
71
72 · If no owner for the specified selection exists, the X server gen‐
73 erates a SelectionNotify event to the requestor with property
74 None.
75
76 The arguments are passed on unchanged in either of the events. There
77 are two predefined selection atoms: PRIMARY and SECONDARY.
78
79 XConvertSelection can generate BadAtom and BadWindow errors.
80
82 BadAtom A value for an Atom argument does not name a defined Atom.
83
84 BadWindow A value for a Window argument does not name a defined Window.
