Signal Documentation
| lostOwner | ( | ) |
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.
- Signal syntax:
QObject.connect(source, SIGNAL("lostOwner()"), target_slot)
| newOwner | ( | long | owner | |
| ) |
This signal is emitted when the selection is successfully claimed by a new owner.
- Parameters:
-
owner the new owner of the selection
- Signal syntax:
QObject.connect(source, SIGNAL("newOwner(Window)"), target_slot)
