39 : * The GroupManager listens at the StarForm for FormComponent insertion and removal as well as
40 : * its properties "Name" and "TabIndex" and updates its Group using this information.
41 : *
42 : * The GroupManager manages a Group in which all Controls are sorted by TabIndex.
43 : * It also manages an array of Groups, in which each FormComponent is assigned a
44 : * Group according to its name.
45 : * Each Group is activated using a Map, if they contain more than one element.
46 : *
47 : * The Groups manage the FormComponents internally using two arrays.
48 : * In the GroupCompArray the Components are sorted by TabIndex and insertion position.
49 : * Because this array is accessed via the FormComponent, we also have the GroupCompAccessArray
50 : * in which the FormComponents are sorted by their storage address.
51 : * Every element of the GroupCompArray has a pointer to the GroupCompArray.
