Interface for widgets which can are used for editing cells
- data CellEditable
- class GObjectClass o => CellEditableClass o
- castToCellEditable :: GObjectClass obj => obj -> CellEditable
- toCellEditable :: CellEditableClass o => o -> CellEditable
- cellEditableStartEditing :: CellEditableClass self => self -> EventM EAny ()
- cellEditableEmitEditingDone :: CellEditableClass self => self -> IO ()
- cellEditableEmitRemoveWidget :: CellEditableClass self => self -> IO ()
- cellEditableEditingCanceled :: CellEditableClass self => Attr self Bool
- cellEditableEditingDone :: CellEditableClass self => Signal self (IO ())
- cellEditableRemoveWidget :: CellEditableClass self => Signal self (IO ())
Detail
The CellEditable
interface must be implemented for widgets to be usable
when editing the contents of a TreeView
cell.
Class Hierarchy
| GInterface
| +----CellEditable
Types
data CellEditable Source
class GObjectClass o => CellEditableClass o Source
castToCellEditable :: GObjectClass obj => obj -> CellEditable Source
toCellEditable :: CellEditableClass o => o -> CellEditable Source
Methods
cellEditableStartEditing :: CellEditableClass self => self -> EventM EAny () Source
Begins editing on a cellEditable
. event
is the Event
that began the editing process.
cellEditableEmitEditingDone :: CellEditableClass self => self -> IO () Source
Emits the cellEditableEditingDone
signal.
cellEditableEmitRemoveWidget :: CellEditableClass self => self -> IO () Source
Emits the cellEditableRemoveWidget
signal.
Attributes
cellEditableEditingCanceled :: CellEditableClass self => Attr self Bool Source
Indicates whether editing on the cell has been canceled.
Default value: False
- Available since Gtk+ version 2.20
Signals
cellEditableEditingDone :: CellEditableClass self => Signal self (IO ()) Source
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 ()) Source
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.
