ARGUMENTS
Specifies the connection to the X server. Specifies the owner of the
specified selection atom. You can pass a window or None. Specifies the
property name. You also can pass None. Specifies the requestor. Spec‐
ifies the selection atom. Specifies the target atom. Specifies the
time. You can pass either a timestamp or CurrentTime.
DESCRIPTION
The XSetSelectionOwner function changes the owner and last-change time
for the specified selection and has no effect if the specified time is
earlier than the current last-change time of the specified selection or
is later than the current X server time. Otherwise, the last-change
time is set to the specified time, with CurrentTime replaced by the
current server time. If the owner window is specified as None, then the
owner of the selection becomes None (that is, no owner). Otherwise, the
owner of the selection becomes the client executing the request.
If the new owner (whether a client or None) is not the same as the cur‐
rent owner of the selection and the current owner is not None, the cur‐
rent owner is sent a SelectionClear event. If the client that is the
owner of a selection is later terminated (that is, its connection is
closed) or if the owner window it has specified in the request is later
destroyed, the owner of the selection automatically reverts to None,
but the last-change time is not affected. The selection atom is unin‐
terpreted by the X server. XGetSelectionOwner returns the owner win‐
dow, which is reported in SelectionRequest and SelectionClear events.
Selections are global to the X server.
XSetSelectionOwner can generate BadAtom and BadWindow errors.
The XGetSelectionOwner function returns the window ID associated with
the window that currently owns the specified selection. If no selec‐
tion was specified, the function returns the constant None. If None is
returned, there is no owner for the selection.
XGetSelectionOwner can generate a BadAtom error.
XConvertSelection requests that the specified selection be converted to
the specified target type: If the specified selection has an owner, the
X server sends a SelectionRequest event to that owner. If no owner for
the specified selection exists, the X server generates a SelectionNo‐
tify event to the requestor with property None.
The arguments are passed on unchanged in either of the events. There
are two predefined selection atoms: PRIMARY and SECONDARY.
XConvertSelection can generate BadAtom and BadWindow errors.
DIAGNOSTICS
A value for an Atom argument does not name a defined Atom. A value for
a Window argument does not name a defined Window.
