How can i open persistent editor which itself closed?
If i use QAbstractItemView::openPersistentEditor() i need to close my editor, how can i called editor which i get when i clicked to item

[Ruzik]

Sorry for my bad english, i try to explain again:
I have QTreeView, when i clicked on the item, standard text editor(QLineEdit) of this item opened.
But i want to open this standart editor(or delegate) independently and u try to use QAbstractItemView::openPersistentEditor(), but if i use this slot i must close this editor.
How can i get method to open stadart editor that closes itself?
