A few queries about Model View Programming

[montylee]

Haven't you seen any example that does that? In general you must be able to return data for both roles - QString for DisplayRole and QIcon or QPixmap for DecorationRole.

I'll try searching the Qt example for the icon thing. I managed to get the icon along with the song name. Here's the code:

if (role == Qt:ecorationRole && index.column() == 0) {
QPixmap pixmap ("icon.png");
return pixmap;
}

So, in the end it was pretty simple to get the icon.

If you don't know which model to use, QStandardItemModel is almost always a good choice. If you are using a database though, you might want to use QSqlQueryModel or one of its descendants.

I have decided to use QAbstractTableModel as it fits my requirements perfectly.

Bad choice.

QList<MyStruct> is much better.

Actually the data from the database is already coming as a QStringList so i have to use a QList of QStringList, so i have no choice here.

By setting a custom delegate and using QStyle::drawPrimitive() and PE_IndicatorCheckBox.

But using custom delegate i think the custom drawing will only be visible to the user when it goes into edit mode. I want the custom drawing to be visible at all times. Currently the normal checkbox (using QCheckBoxRole) is visible at all times, so i just want to add custom drawing to it. But i am not sure how to draw it as it's not a real checkbox, so a normal custom delegate might not work.
