Description

Interface for widgets that can be used for editing cells

The Gnome::Gtk4::R-CellEditable interface must be implemented for widgets to be usable to edit the contents of a Gnome::Gtk4::TreeView cell. It provides a way to specify how temporary widgets should be configured for editing, get the new value, etc.

Methods

editing-done

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

Emits the Gnome::Gtk4::R-CellEditable::editing-done` signal.

method editing-done ( )

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

Emits the Gnome::Gtk4::R-CellEditable::remove-widget` signal.

method remove-widget ( )

start-editing

Begins editing on a $cell-editable.

The Gnome::Gtk4::CellRenderer for the cell creates and returns a Gnome::Gtk4::R-CellEditable from gtk_cell_renderer_start_editing(), configured for the Gnome::Gtk4::CellRenderer type.

.start-editing() can then set up $cell-editable suitably for editing a cell, e.g. making the Esc key emit Gnome::Gtk4::R-CellEditable::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.

method start-editing ( N-Object() $event )

$event; The Gnome::Gdk4::Event that began the editing process, or undefined if editing was initiated programmatically.

Signals

editing-done

This signal is a sign for the cell renderer to update its value from the $cell-editable.

Implementations of Gnome::Gtk4::R-CellEditable are responsible for emitting this signal when they are done editing, e.g. Gnome::Gtk4::Entry 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 Gnome::Gtk4::CellRenderer, etc.

.editing-done() is a convenience method for emitting Gnome::Gtk4::R-CellEditable::editing-done`.

method handler (
  Int :$_handle_id,
  N-GObject :$_native-object,
  Gnome::Gtk4::CellEditable :$_widget,
  *C<user>-options
)

$_handle_id; The registered event handler id.
$_native-object; The native object provided by the Raku object which registered this event. This a native Gnome::Gtk4::CellEditable object.
$_widget; The object which registered the signal. User code may have left the object going out of scope.
user-options; A list of named arguments provided at the .register-signal() method from Gnome::GObject::Object.

remove-widget

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 Gnome::Gtk4::R-CellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the Gnome::Gtk4::R-CellEditable::editing-done` signal, to give the cell renderer a chance to update the cell's value before the widget is removed.

.remove-widget() is a convenience method for emitting Gnome::Gtk4::R-CellEditable::remove-widget`.

method handler (
  Int :$_handle_id,
  N-GObject :$_native-object,
  Gnome::Gtk4::CellEditable :$_widget,
  *C<user>-options
)

$_handle_id; The registered event handler id.
$_native-object; The native object provided by the Raku object which registered this event. This a native Gnome::Gtk4::CellEditable object.
$_widget; The object which registered the signal. User code may have left the object going out of scope.
user-options; A list of named arguments provided at the .register-signal() method from Gnome::GObject::Object.
