Flags: Run Last
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 signal_editing_done() are to capture the edited value, disconnect the cell_editable from signals on the GtkCellRenderer
, 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 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::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 GtkCellRenderer
for the cell creates and returns a GtkCellEditable
from Gtk::CellRenderer::start_editing(), configured for the GtkCellRenderer
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.
