Trait containing all CellEditable methods.

Implementors

CellEditable, ComboBoxText, ComboBox, Entry, SpinButton

Required methods

Emits the GtkCellEditable::editing-done signal.

Emits the GtkCellEditable::remove-widget signal.

Indicates whether editing on the cell has been canceled.

Indicates whether editing on the cell has been canceled.

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

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 ::editing-done are to capture the edited value, disconnect the cell_editable from signals on the CellRenderer, etc.

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

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 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.

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