36 Proxy model used for filtering and sorting informations about xdxf dictionaries.
37 It allow to filter dictionaries based on their langages
39 class DictsProxyModel : public QSortFilterProxyModel
43 DictsProxyModel(QObject *parent = 0): QSortFilterProxyModel(parent){
48 Returns currently setted language used to filter dictionaries
49 based on dictionarie's language from
51 QString from() { return _from;}
54 Returns currently setted language used to filter dictionaries
55 based on dictionarie's language to
57 QString to() {return _to;}
61 Sets currently setted language used to filter dictionaries based
62 on dictionarie's language from
64 void setFrom(QString from) { _from = from; invalidateFilter(); }
67 Sets currently setted language used to filter dictionaries
68 based on dictionarie's language to
70 void setTo(QString to) {_to = to; invalidateFilter();}
73 //! Filtering passed row
74 bool filterAcceptsRow(int source_row, const QModelIndex&) const {
75 QString sourceFrom = sourceModel()->data(
76 sourceModel()->index(source_row, 0)).toString();
77 QString sourceTo = sourceModel()->data(
78 sourceModel()->index(source_row, 1)).toString();
80 return ((_from.isEmpty() || sourceFrom == _from) &&
81 (_to.isEmpty() || sourceTo == _to));
85 Sorting, if sort column is set to column containing size of dictionary,
86 string containing size of it is converted to fload and compared to
89 bool lessThan(const QModelIndex &left, const QModelIndex &right) const {
90 if(sortColumn() == 3) {
91 QString l = left.model()->data(left).toString();
94 QString r = right.model()->data(right).toString();
97 float lNumber = l.toFloat();
98 float rNumber = r.toFloat();
100 return (lNumber < rNumber);
103 QSortFilterProxyModel::lessThan(left, right);
