XSetSelectionOwner(3)                          XLIB FUNCTIONS                          XSetSelectionOwner(3)



NAME
       XSetSelectionOwner, XGetSelectionOwner, XConvertSelection - manipulate window selection

SYNTAX
       int XSetSelectionOwner(Display *display, Atom selection, Window owner, Time time);

       Window XGetSelectionOwner(Display *display, Atom selection);

       int XConvertSelection(Display *display, Atom selection, Atom target, Atom property, Window requestor,
              Time time);

ARGUMENTS
       display   Specifies the connection to the X server.

       owner     Specifies the owner of the specified selection atom.  You can pass a window or None.

       property  Specifies the property name.  You also can pass None.

       requestor Specifies the requestor.

       selection Specifies the selection atom.

       target    Specifies the target atom.

       time      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 speci-fied specified
       fied 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 current owner of the selection and
       the current owner is not None, the current 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 uninterpreted by
       the X server.  XGetSelectionOwner returns the owner window, 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 selection 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 SelectionNotify 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
       BadAtom   A value for an Atom argument does not name a defined Atom.

       BadWindow A value for a Window argument does not name a defined Window.
