Using Filters to Extract Information from a QStandardItemModel
I'm working on a project where the user can select items from a treeview, the treeview is made up of QStandardItemModel objects which contain the column information.
How can I retrieve information from these objects? I have a function called get_category_item(item) which I would expect to return a pointer to a QStandardItem object. However, when I try to call it with a QStandardItemModel, it returns a pointer to a QStandardItem which I believe is a subclass.
This is the get_category_item function:
QStandardItem * get_category_item(QStandardItemModel *model, QStandardItem *parent) {
//parent has been set in another function as the root item
QStandardItem * item = parent->child(parent->indexOfChild(parent, 0) + 1);
//if(item == 0) //item is a special root item
//{
// return 0;
//}
while(item) {
if(item->data(Qt::DisplayRole).toString() == "ID") {
item = item->parent();
}
else if(item->data(Qt::DisplayRole).toString() == "Name") {
item = item->parent(); ac619d1d87
