Example 6 with PanelEquations

the class AddPart method centerOf.

/**
 *        Determine the anchor position for a set of new parts.
 *        The main approach is to approximate the center of the viewport when the parent part is displayed.
 *        If that is not possible, the fallback is the average position of existing parts.
 *        If there are no existing parts, the position is set arbitrarily to (100,100). This gives a small
 *        margin from the edge for nice appearance, while not straying far from (0,0).
