Hi,
No need of QITemDelegate to display a checkbox.
(this is extracted from an implementation of QAbstractItemModel)
@Override
public ItemFlags flags(QModelIndex index) {
return new ItemFlags(new ItemFlag[] {
ItemFlag.ItemIsSelectable, ItemFlag.ItemIsEnabled,
ItemFlag.ItemIsUserCheckable });
}
than in setData() and data(), you need to handle the CheckStateRole.
For example :
@Override
public boolean setData(QModelIndex index, Object value, int role) {
if (role == ItemDataRole.CheckStateRole) {
...
return true;
}
return super.setData(index, value, role);
}
@Override
public Object data(QModelIndex index, int role) {
...
switch (role) {
case ItemDataRole.CheckStateRole:
...
}
return null;
}
