.close_window(num) ⇒ Object

Закрыть окно с номером num. Окна нумируются в порядке их открытия. Нумирация начинается с 0. Если необходимо закрыть текущее окно, то перед закрытием необходимо переключиться на другое окно. После закрытия окна происходить их переупорядочивание. Так, например, если было закрыто первое окно (num = 0), то второе окно станет первым (было num = 1, стало num = 0) и т.д.

Examples:

context "Example" do

  should 'TODO something' do
    Unit.close_window 2
    ...

Parameters:

  • num (Fixnum) —

    номер окна

Raises:

  • (ArgumentError)
