Required Methods§
sourcefn activate(
&self,
event: impl AsRef<Event>,
widget: &impl IsA<Widget>,
path: &str,
background_area: &Rectangle,
cell_area: &Rectangle,
flags: CellRendererState
) -> bool
fn activate( &self, event: impl AsRef<Event>, widget: &impl IsA<Widget>, path: &str, background_area: &Rectangle, cell_area: &Rectangle, flags: CellRendererState ) -> bool
Passes an activate event to the cell renderer for possible processing.
Some cell renderers may use events; for example, CellRendererToggle
toggles when it gets a mouse click.
Deprecated since 4.10
event
widget
widget that received the event
path
widget-dependent string representation of the event location;
e.g. for TreeView, a string representation of TreePath
background_area
background area as passed to gtk_cell_renderer_render()
cell_area
cell area as passed to gtk_cell_renderer_render()
flags
render flags
Returns
true if the event was consumed/handled
