pub trait AsyncPosition<Pos> {
    // Required method
    fn position(index: usize) -> Pos;
Expand description

Returns the position of an element inside a container like gtk::Grid where the position isn’t clearly defined by the index.

Unlike Position, this trait doesn’t get access to self, because the model might not be initialized when the widgets are updated in the factory.

Required Methods§


fn position(index: usize) -> Pos

Returns the position.

This function can be called very often if widgets are moved a lot, so it should be cheap to call.
