Required Methods

fn activate( &self, context: &impl IsA<CellAreaContext>, widget: &impl IsA<Widget>, cell_area: &Rectangle, flags: CellRendererState, edit_only: bool ) -> bool

Activates @self, usually by activating the currently focused cell, however some subclasses which embed widgets in the area can also activate a widget if it currently has the focus.

Deprecated since 4.10

context

the CellAreaContext in context with the current row data

widget

the Widget that @self is rendering on

cell_area

the size and location of @self relative to @widget’s allocation

flags

the CellRendererState flags for @self for this row of data.

edit_only

if true then only cell renderers that are CellRendererMode::Editable will be activated.

Returns

Whether @self was successfully activated.

fn activate_cell( &self, widget: &impl IsA<Widget>, renderer: &impl IsA<CellRenderer>, event: impl AsRef<Event>, cell_area: &Rectangle, flags: CellRendererState ) -> bool

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

event

the gdk::Event for which cell activation should occur

cell_area

the gdk::Rectangle in @widget relative coordinates of @renderer for the current row.

flags

the CellRendererState for @renderer

Returns

whether cell activation was successful
