Interface for widgets which are used for editing cells.
The CellEditable interface must be implemented for widgets to be usable when editing the contents of a TreeView cell.

This signal is a sign for the cell renderer to update its value from the cell_editable.
Implementations of Gtk::CellEditable
are responsible for emitting this signal when they are done editing, e.g. Gtk::Entry
emits this signal when the user presses Enter. Typical things to do in a handler for signal_editing_done() are to capture the edited value, disconnect the cell_editable from signals on the Gtk::CellRenderer
, etc.
Gtk::CellEditable::editing_done() is a convenience method for emitting GtkCellEditable::editing-done
.
Glib::SignalProxy< void()> Gtk::CellEditable::signal_remove_widget | ( | ) |
void on_my_remove_widget()
Flags: Run Last
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 Gtk::CellEditable
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::CellEditable::remove_widget() is a convenience method for emitting GtkCellEditable::remove-widget
.
void Gtk::CellEditable::start_editing | ( | const Glib::RefPtr< const Gdk::Event > & | event | ) |
Begins editing on a cell_editable.
The Gtk::CellRenderer
for the cell creates and returns a Gtk::CellEditable
from Gtk::CellRenderer::start_editing(), configured for the Gtk::CellRenderer
type.
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.
event | The Gdk::Event that began the editing process, or nullptr if editing was initiated programmatically. |
