This is used by CellArea subclasses when handling events to activate cells, the base CellArea class activates cells for keyboard events for free in its own GtkCellArea->activate() implementation.

§Deprecated since 4.10
§widget

Events handled by focus siblings can also activate the given focusable @renderer.

§Deprecated since 4.10
§renderer

the CellRenderer expected to have focus

§sibling

source

fn copy_context(&self, context: &impl IsA<CellAreaContext>) -> CellAreaContext

👎Deprecated: Since 4.10

This is sometimes needed for cases where rows need to share alignments in one orientation but may be separately grouped in the opposing orientation.

For instance, IconView creates all icons (rows) to have the same width and the cells theirin to have the same horizontal alignments. However each row of icons may have a separate collective height. IconView uses this to request the heights of each row based on a context which was already used to request all the row widths that are to be displayed.

Creates a CellAreaContext to be used with @self for all purposes. CellAreaContext stores geometry information for rows for which it was operated on, it is important to use the same context for the same row of data at all times (i.e. one should render and handle events with the same CellAreaContext which was used to request the size of those rows of data).

§Deprecated since 4.10
§Returns

a newly created CellAreaContext which can be used with @self.

👎Deprecated: Since 4.10

This should be called by the @self’s owning layout widget when focus is to be passed to @self, or moved within @self for a given @direction and row data.

Implementing CellArea classes should implement this method to receive and navigate focus in its own way particular to how it lays out cells.

§Deprecated since 4.10
§direction

the DirectionType

§Returns

true if focus remains inside @self as a result of this call.

source

fn foreach<P: FnMut(&CellRenderer) -> bool>(&self, callback: P)

👎Deprecated: Since 4.10

Retrieves a cell area’s initial minimum and natural height.

@self will store some geometrical information in @context along the way; when requesting sizes over an arbitrary number of rows, it’s not important to check the @minimum_height and @natural_height of this call but rather to consult gtk_cell_area_context_get_preferred_height() after a series of requests.

👎Deprecated: Since 4.10

Retrieves a cell area’s minimum and natural height if it would be given the specified @width.

@self stores some geometrical information in @context along the way while calling gtk_cell_area_get_preferred_width(). It’s important to perform a series of gtk_cell_area_get_preferred_width() requests with @context first and then call gtk_cell_area_get_preferred_height_for_width() on each cell area individually to get the height for width of each fully requested row.

If at some point, the width of a single row changes, it should be requested with gtk_cell_area_get_preferred_width() again and then the full width of the requested rows checked again with gtk_cell_area_context_get_preferred_width().

@self stores some geometrical information in @context along the way while calling gtk_cell_area_get_preferred_height(). It’s important to perform a series of gtk_cell_area_get_preferred_height() requests with @context first and then call gtk_cell_area_get_preferred_width_for_height() on each cell area individually to get the height for width of each fully requested row.

If at some point, the height of a single row changes, it should be requested with gtk_cell_area_get_preferred_height() again and then the full height of the requested rows checked again with gtk_cell_area_context_get_preferred_height().

👎Deprecated: Since 4.10

This is a convenience function for CellArea implementations to request size for cell renderers. It’s important to use this function to request size and then use gtk_cell_area_inner_cell_area() at render and event time since this function will add padding around the cell for focus painting.

👎Deprecated: Since 4.10

Explicitly stops the editing of the currently edited cell.

If @canceled is true, the currently edited cell renderer will emit the ::editing-canceled signal, otherwise the the ::editing-done signal will be emitted on the current edit widget.
