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

the Widget that @self is rendering onto

§renderer

the CellRenderer in @self to activate

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

§Deprecated since 4.10
§renderer

the CellRenderer expected to have focus

§sibling

§attribute

an attribute on the renderer

§Returns

the model column, or -1

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.

source

fn event( &self, context: &impl IsA<CellAreaContext>, widget: &impl IsA<Widget>, event: impl AsRef<Event>, cell_area: &Rectangle, flags: CellRendererState ) -> i32

the Widget that @self is rendering to

§event

the gdk::Event to handle

§cell_area

the @widget relative coordinates for @self

§flags

the CellRendererState for @self in this row.

§Returns

true if the event was handled by @self.

source

fn focus(&self, direction: DirectionType) -> bool

👎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().

§Deprecated since 4.10

@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().

the @widget relative coordinates for @self’s background

§cell_area

the @widget relative coordinates for @self

§flags

the CellRendererState for @self in this row.

§paint_focus

whether @self should paint focus on focused cells for focused rows or not.

fn stop_editing(&self, canceled: bool)

👎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.

See gtk_cell_area_get_edited_cell() and gtk_cell_area_get_edit_widget().

§Deprecated since 4.10
§canceled

whether editing was canceled.

source

fn connect_add_editable<F: Fn(&Self, &CellRenderer, &CellEditable, &Rectangle, TreePath) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10

Indicates that editing has started on @renderer and that @editable should be added to the owning cell-layouting widget at @cell_area.

§renderer

the CellRenderer that started the edited

§editable

the CellEditable widget to add

§cell_area

the Widget relative gdk::Rectangle coordinates where @editable should be added

§path

the TreePath string this edit was initiated for

source

fn connect_apply_attributes<F: Fn(&Self, &TreeModel, &TreeIter, bool, bool) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10

This signal is emitted whenever applying attributes to @area from @model

§model

the TreeModel to apply the attributes from

§iter

the TreeIter indicating which row to apply the attributes of

§is_expander

whether the view shows children for this row

§is_expanded

whether the view is currently showing the children of this row

source

fn connect_focus_changed<F: Fn(&Self, &CellRenderer, TreePath) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10

Indicates that focus changed on this @area. This signal is emitted either as a result of focus handling or event handling.

It’s possible that the signal is emitted even if the currently focused renderer did not change, this is because focus may change to the same renderer in the same cell area for a different row of data.

§renderer

the CellRenderer that has focus

§path

the current TreePath string set for @area

source

fn connect_remove_editable<F: Fn(&Self, &CellRenderer, &CellEditable) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10

Indicates that editing finished on @renderer and that @editable should be removed from the owning cell-layouting widget.

§renderer

the CellRenderer that finished editeding

§editable

the CellEditable widget to remove
