GI.Gtk.Interfaces.CellEditable

The CellEditable interface must be implemented for widgets to be usable to edit the contents of a TreeView cell. It provides a way to specify how temporary widgets should be configured for editing, get the new value, etc.

editingDone

cellEditableEditingDone

Arguments

:: (HasCallStack, MonadIO m, IsCellEditable a)

=> a

cellEditable: A CellEditable

-> m ()

Emits the CellEditable::editingDone signal.

removeWidget

cellEditableRemoveWidget

Arguments

:: (HasCallStack, MonadIO m, IsCellEditable a)

=> a

cellEditable: A CellEditable

-> m ()

Emits the CellEditable::removeWidget signal.

startEditing

cellEditableStartEditing

Arguments

:: (HasCallStack, MonadIO m, IsCellEditable a)

=> a

cellEditable: A CellEditable

-> Maybe Event

event: The Event that began the editing process, or Nothing if editing was initiated programmatically

-> m ()

Begins editing on a cellEditable.

The CellRenderer for the cell creates and returns a CellEditable from cellRendererStartEditing, configured for the CellRenderer type.

cellEditableStartEditing can then set up cellEditable suitably for editing a cell, e.g. making the Esc key emit CellEditable::editingDone.

Note that the cellEditable is created on-demand for the current edit; its lifetime is temporary and does not persist across other edits and/or cells.

Properties

editingCanceled

Indicates whether editing on the cell has been canceled.

Since: 2.20

constructCellEditableEditingCanceled :: (IsCellEditable o, MonadIO m) => Bool -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “editing-canceled” property. This is rarely needed directly, but it is used by new.

getCellEditableEditingCanceled :: (MonadIO m, IsCellEditable o) => o -> m Bool

Get the value of the “editing-canceled” property. When overloading is enabled, this is equivalent to

get cellEditable #editingCanceled

setCellEditableEditingCanceled :: (MonadIO m, IsCellEditable o) => o -> Bool -> m ()

Set the value of the “editing-canceled” property. When overloading is enabled, this is equivalent to

set cellEditable [ #editingCanceled := value ]

Signals

editingDone

type CellEditableEditingDoneCallback = 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 emits this signal when the user presses Enter. Typical things to do in a handler for editingDone are to capture the edited value, disconnect the cellEditable from signals on the CellRenderer, etc.

cellEditableEditingDone is a convenience method for emitting CellEditable::editingDone.

afterCellEditableEditingDone :: (IsCellEditable a, MonadIO m) => a -> ((?self :: a) => CellEditableEditingDoneCallback) -> m SignalHandlerId

Connect a signal handler for the editingDone signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after cellEditable #editingDone callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onCellEditableEditingDone :: (IsCellEditable a, MonadIO m) => a -> ((?self :: a) => CellEditableEditingDoneCallback) -> m SignalHandlerId

Connect a signal handler for the editingDone signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on cellEditable #editingDone callback

removeWidget

type CellEditableRemoveWidgetCallback = IO ()

This signal is meant to indicate that the cell is finished editing, and the cellEditable widget is being removed and may subsequently be destroyed.

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

cellEditableRemoveWidget is a convenience method for emitting CellEditable::removeWidget.

afterCellEditableRemoveWidget :: (IsCellEditable a, MonadIO m) => a -> ((?self :: a) => CellEditableRemoveWidgetCallback) -> m SignalHandlerId

Connect a signal handler for the removeWidget signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after cellEditable #removeWidget callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onCellEditableRemoveWidget :: (IsCellEditable a, MonadIO m) => a -> ((?self :: a) => CellEditableRemoveWidgetCallback) -> m SignalHandlerId

Connect a signal handler for the removeWidget signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on cellEditable #removeWidget callback
