380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	44 * Typically, scroll bars will be made up of five areas:

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	52 * Based on their style, scroll bars are either <code>HORIZONTAL</code>
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	53 * (which have a left facing button for decrementing the value and a
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	54 * right facing button for incrementing it) or <code>VERTICAL</code>

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	58 * On some platforms, the size of the scroll bar's thumb can be
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	59 * varied relative to the magnitude of the range of values it
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	60 * represents (that is, relative to the difference between its
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	61 * maximum and minimum values). Typically, this is used to
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	62 * indicate some proportional value such as the ratio of the
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	63 * visible area of a document to the total amount of space that
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	64 * it would take to display it. DWT supports setting the thumb

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	66 * case the appearance of the scroll bar will not change.

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	68 * Scroll bars are created by specifying either <code>H_SCROLL</code>,
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	69 * <code>V_SCROLL</code> or both when creating a <code>Scrollable</code>.
