foreach or alike

this code works without the foreach but im getting the first image for each item and its using the same image for all of them

what im trying to do is for each string assign the string filename to the item.... still cant get it working properly ...

foreach works with containers what is your container that you want to iterate over?

[prophet0]

using QSQLQueryModel as my container

[Lykurg]

you can't use QSQLQueryModel in a foreach loop. It also isn't necessary since the while loop is there already.

Further, what do you try to achieve? You code looks "strange":

iListView->setStyleSheet(stylesheet);

iListView->setStyleSheet(stylesheet);

will be overwritten each loop, that only the last one will take effect.

im trying to change the item image for each query value returned

How about subclassing the model and reimplementing data() to return the proper icon for Qt::DecorationRole of each respective index?

[prophet0]

Sorry but would you be able to show an example of subclassing a model that seems like the perfect way to go

[wysota]

Don't you know how to implement a subclass in C++?

class MyModel : public QSqlQueryModel {
public:
  MyModel(...) : QSqlQueryModel(...) {}
 
  QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const {
    // put your stuff here
  }
};

class MyModel : public QSqlQueryModel {
public:
  MyModel(...) : QSqlQueryModel(...) {}

  QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const {
    // put your stuff here
  }
};
