Trait containing all CellEditable
methods.
Implementors
Required Methods§
sourcefn editing_done(&self)
fn editing_done(&self)
Emits the GtkCellEditable::editing-done
signal.
Deprecated since 4.10
sourcefn remove_widget(&self)
fn remove_widget(&self)
Emits the GtkCellEditable::remove-widget
signal.
Deprecated since 4.10
sourcefn start_editing(&self, event: Option<impl AsRef<Event>>)
fn start_editing(&self, event: Option<impl AsRef<Event>>)
Begins editing on a @self.
The CellRenderer
for the cell creates and returns a CellEditable
from
gtk_cell_renderer_start_editing(), configured for the CellRenderer
type.
gtk_cell_editable_start_editing() can then set up @self suitably for
editing a cell, e.g. making the Esc key emit GtkCellEditable::editing-done
.
Note that the @self 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
None
if editing was initiated programmatically
sourcefn is_editing_canceled(&self) -> bool
fn is_editing_canceled(&self) -> bool
Indicates whether editing on the cell has been canceled.
sourcefn set_editing_canceled(&self, editing_canceled: bool)
fn set_editing_canceled(&self, editing_canceled: bool)
Indicates whether editing on the cell has been canceled.
sourcefn connect_editing_done<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_editing_done<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
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.
gtk_cell_editable_editing_done() is a convenience method
for emitting GtkCellEditable::editing-done
.
sourcefn connect_remove_widget<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_remove_widget<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
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.
gtk_cell_editable_remove_widget() is a convenience method
for emitting GtkCellEditable::remove-widget
.
