Constructor & Destructor Documentation

KSelectionWatcher::KSelectionWatcher ( Atom  selection, int  screen = -1, QObject *  parent = NULL  )

explicit

This constructor initializes the object, but doesn't perform any operation on the selection.

Parameters

selection	atom representing the manager selection
screen	X screen, or -1 for default
parent	parent object, or NULL if there is none

Definition at line 403 of file kmanagerselection.cpp.

KSelectionWatcher::KSelectionWatcher ( const char *  selection, int  screen = -1, QObject *  parent = NULL  )

explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This constructor accepts the selection name and creates the appropriate atom for it automatically.

Parameters

selection	name of the manager selection
screen	X screen, or -1 for default
parent	parent object, or NULL if there is none

Member Function Documentation

void KSelectionWatcher::filterEvent

(

XEvent *

ev_P

)

Definition at line 459 of file kmanagerselection.cpp.

void KSelectionWatcher::lostOwner ( )

signal

This signal is emitted when the selection is given up, i.e.

there's no owner. Note that the selection may be immediatelly claimed again, so the newOwner() signal may be emitted right after this one. It's safe to delete the instance in a slot connected to this signal.

void KSelectionWatcher::newOwner ( Window  owner )

signal

This signal is emitted when the selection is successfully claimed by a new owner.

Parameters

owner

the new owner of the selection

Window KSelectionWatcher::owner

(

)

Return the current owner of the manager selection, if any.

Note that if the event informing about the owner change is still in the input queue, newOwner() might have been emitted yet.
