6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	31 * Instances of this class are selectable user interface
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	32 * objects that represent a range of positive, numeric values.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	33 * <p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	34 * At any given moment, a given scroll bar will have a
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	35 * single 'selection' that is considered to be its
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	36 * value, which is constrained to be within the range of
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	37 * values the scroll bar represents (that is, between its
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	38 * <em>minimum</em> and <em>maximum</em> values).
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	39 * </p><p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	40 * Typically, scroll bars will be made up of five areas:
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	41 * <ol>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	42 * <li>an arrow button for decrementing the value</li>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	43 * <li>a page decrement area for decrementing the value by a larger amount</li>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	44 * <li>a <em>thumb</em> for modifying the value by mouse dragging</li>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	45 * <li>a page increment area for incrementing the value by a larger amount</li>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	46 * <li>an arrow button for incrementing the value</li>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	47 * </ol>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	48 * Based on their style, scroll bars are either <code>HORIZONTAL</code>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	49 * (which have a left facing button for decrementing the value and a
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	50 * right facing button for incrementing it) or <code>VERTICAL</code>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	51 * (which have an upward facing button for decrementing the value
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * and a downward facing buttons for incrementing it).
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * </p><p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * On some platforms, the size of the scroll bar's thumb can be
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * varied relative to the magnitude of the range of values it
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * represents (that is, relative to the difference between its
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * maximum and minimum values). Typically, this is used to
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * indicate some proportional value such as the ratio of the
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * visible area of a document to the total amount of space that
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * it would take to display it. SWT supports setting the thumb
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * size even if the underlying platform does not, but in this
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * case the appearance of the scroll bar will not change.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	63 * </p><p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * Scroll bars are created by specifying either <code>H_SCROLL</code>,
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * <code>V_SCROLL</code> or both when creating a <code>Scrollable</code>.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	66 * They are accessed from the <code>Scrollable</code> using
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	67 * <code>getHorizontalBar</code> and <code>getVerticalBar</code>.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	68 * </p><p>
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	69 * Note: Scroll bars are not Controls. On some platforms, scroll bars
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	70 * that appear as part of some standard controls such as a text or list
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	71 * have no operating system resources and are not children of the control.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	72 * For this reason, scroll bars are treated specially. To create a control
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	73 * that looks like a scroll bar but has operating system resources, use
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	74 * <code>Slider</code>.
