It is used to reflect the differences in this ordering * between Western alphabets, Middle Eastern (such as Hebrew), and Far * Eastern (such as Japanese). * <p> * Fundamentally, this governs items (such as characters) which are laid out * in lines, with the lines then laid out in a block. This also applies * to items in a widget: for example, in a check box where the box is * positioned relative to the text. * <p> * There are four different orientations used in modern languages * as in the following table.<br> * <pre> * LT RT TL TR * A B C C B A A D G G D A * D E F F E D B E H H E B * G H I I H G C F I I F C * </pre><br> * (In the header, the two-letter abbreviation represents the item direction * in the first letter, and the line direction in the second. For example, * LT means "items left-to-right, lines top-to-bottom", * TL means "items top-to-bottom, lines left-to-right", and so on.) * <p> * The orientations are: * <ul> * <li>LT - Western Europe (optional for Japanese, Chinese, Korean) * <li>RT - Middle East (Arabic, Hebrew) * <li>TR - Japanese, Chinese, Korean * <li>TL - Mongolian * </ul> * Components whose view and controller code depends on orientation * should use the <code>isLeftToRight()</code> and * <code>isHorizontal()</code> methods to * determine their behavior.
