CellEditableProtocol

public protocol CellEditableProtocol : WidgetProtocol

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

The CellEditableProtocol protocol exposes the methods and properties of an underlying GtkCellEditable instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CellEditable. Alternatively, use CellEditableRef as a lighweight, unowned reference if you already have an instance you just want to use.

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

    Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing, e.g. GtkEntry emits this signal when the user presses Enter. Typical things to do in a handler for editing-done are to capture the edited value, disconnect the cell_editable from signals on the GtkCellRenderer, etc.

    gtk_cell_editable_editing_done() is a convenience method for emitting GtkCellEditable::editing-done.

    Note

    This represents the underlying editing-done signal

    Declaration

    Swift

    @discardableResult
@inlinable
func onEditingDone(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: CellEditableRef) -> Void) -> Int

    Parameters

    flags

    Flags
    unownedSelf

    Reference to instance of self
    handler

    The signal handler to call Run the given callback whenever the editingDone signal is emitted

  • editingDoneSignal Extension method

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

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

    gtk_cell_editable_remove_widget() is a convenience method for emitting GtkCellEditable::remove-widget.

    Note

    This represents the underlying remove-widget signal

    Declaration

    Swift

    @discardableResult
@inlinable
func onRemoveWidget(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: CellEditableRef) -> Void) -> Int

    Parameters

    flags

    Flags
    unownedSelf

    Reference to instance of self

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

    Note

    This represents the underlying notify::editing-canceled signal

    Declaration

    Swift

    @discardableResult
@inlinable
func onNotifyEditingCanceled(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: CellEditableRef, _ pspec: ParamSpecRef) -> Void) -> Int

CellEditable Interface: CellEditableProtocol extension (methods and fields)

  • editingDone() Extension method

    Emits the GtkCellEditable::editing-done signal.

    Declaration

    Swift

func editingDone()

  • removeWidget() Extension method

    Emits the GtkCellEditable::remove-widget signal.

    Declaration

  • startEditing(event:) Extension method

    Begins editing on a cell_editable.

    The GtkCellRenderer for the cell creates and returns a GtkCellEditable from gtk_cell_renderer_start_editing(), configured for the GtkCellRenderer type.

    gtk_cell_editable_start_editing() can then set up cell_editable suitably for editing a cell, e.g. making the Esc key emit GtkCellEditable::editing-done.

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