Function vgtk::run_dialog

pub fn run_dialog<C: 'static + Component>(
    parent: Option<&Window>
) -> impl Future<Output = Result<ResponseType, Canceled>>

Launch a Dialog component as a modal dialog.

The parent window will be blocked until it resolves.

It returns a Future which resolves either to Ok(ResponseType) when the response signal is emitted, or to Err(Canceled) if the dialog is destroyed before the user responds to it.
