Signals

cellEditableEditingDone :: CellEditableClass self => Signal self (IO ())

This signal is a sign for the cell renderer to update its value from the cellEditable.

Implementations of CellEditable are responsible for emitting this signal when they are done editing, e.g. Entry is emitting it when the user presses Enter.

cellEditableEmitEditingDone is a convenience method for emitting ::editing-done.

cellEditableRemoveWidget :: CellEditableClass self => Signal self (IO ())

This signal is meant to indicate that the cell is finished editing, and the widget may now be destroyed.

Implementations of CellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the cellEditableEditingDone signal, to give the cell renderer a chance to update the cell's value before the widget is removed.

cellEditableEmitRemoveWidget is a convenience method for emitting ::remove-widget.
