Zusaetzlich horcht er bei den FormComponents an den Properties 44 "Name" und "TabIndex". Mit diesen Infos aktualisiert er seine Gruppen. 45 46 Der GroupManager verwaltet eine Gruppe, in der alle Controls nach TabIndex 47 geordnet sind, und ein Array von Gruppen, in dem jede FormComponent noch 48 einmal einer Gruppe dem Namen nach zugeordnet wird. 49 Die einzelnen Gruppen werden ueber eine Map aktiviert, wenn sie mehr als 50 ein Element besitzen. 51 52 Die Gruppen verwalten intern die FormComponents in zwei Arrays. In dem 53 GroupCompArray werden die Components nach TabIndex und Einfuegeposition 54 sortiert. Da auf dieses Array ueber die FormComponent zugegriffen 55 wird, gibt es noch das GroupCompAccessArray, in dem die FormComponents 56 nach ihrer Speicheradresse sortiert sind. Jedes Element des 57 GroupCompAccessArrays ist mit einem Element des GroupCompArrays verpointert. 58 59 ========================================================================*/ 60 61 //......................................................................... 62 namespace frm 63 { 64 //......................................................................... 65 66 //======================================================================== 67 template <class ELEMENT, class LESS_COMPARE> insert_sorted(::std::vector<ELEMENT> & _rArray,const ELEMENT & _rNewElement,const LESS_COMPARE & _rCompareOp)68 sal_Int32 insert_sorted(::std::vector<ELEMENT>& _rArray, const ELEMENT& _rNewElement, const LESS_COMPARE& _rCompareOp) 69 { 70 typename ::std::vector<ELEMENT>::iterator aInsertPos = lower_bound( 71 _rArray.begin(), 72 _rArray.end(), 73 _rNewElement, 74 _rCompareOp 75 );
