40 fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	28 * <code>FillLayout</code> is the simplest layout class. It lays out
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	29 * controls in a single row or column, forcing them to be the same size.
0 380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	30 * <p>
40 fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	31 * Initially, the controls will all be as tall as the tallest control,
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	32 * and as wide as the widest. <code>FillLayout</code> does not wrap,
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	33 * but you can specify margins and spacing. You might use it to
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	34 * lay out buttons in a task bar or tool bar, or to stack checkboxes
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	35 * in a <code>Group</code>. <code>FillLayout</code> can also be used
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	36 * when a <code>Composite</code> only has one child. For example,
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	37 * if a <code>Shell</code> has a single <code>Group</code> child,
fbe68c33eeee Sync layout with dwt-linux Frank Benoit <benoit@tionex.de> parents: 8 diff changeset	38 * <code>FillLayout</code> will cause the <code>Group</code> to
0 380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	39 * completely fill the <code>Shell</code> (if margins are 0).

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	45 * children are always the same size, and they fill all available space.
