XSetSelectionOwner, XGetSelectionOwner, XConvertSelection - manipulate window selection

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.

       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 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.

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.
