6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	84 * IMPORTANT: Do not define circular attachments. For example, do not attach

6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	86 * and then attach the left edge of <code>button2</code> to the right edge of
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	87 * <code>button1</code>. This will over constrain the layout, causing undefined
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	88 * behavior. The algorithm will terminate, but the results are undefined.

6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	222 * since C is not 0 or 1, it must be a fraction, U / V.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	223 * The offset D is the distance from CX to the bottom edge
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	224 * of the control. This represents a fraction of the form
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	225 * (1 - C)X. Since the height of a fraction of the form is
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	226 * known, the height of the entire form can be found by setting
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	227 * (1 - C)X = D. We solve this equation for X in terms of U
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	228 * and V, giving us X = (U * D) / (U - V). Similarly, if the
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	229 * offset D is negative, the control is positioned above CX.
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	230 * The offset -B is the distance from the top edge of the control
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	231 * to CX. We can find the height of the entire form by setting
6dd524f61e62 add dwt win and basic java stuff Frank Benoit <benoit@tionex.de> parents: diff changeset	232 * CX = -B. Solving in terms of U and V gives us X = (-B * V) / U.
