QTreeWidget findItems or filter by icon

Question

I'm using QTreeWidget with icons and strings data.

Right now I'm using my own filter function to filter out string via QTreeWidget::findItems function and it's works pretty good.

BUT, how can I filter/findItems by icons ?

The Qt findItems functions can get only strings as input...

Any suggestions ?

Try this:

QTreeWidgetItem* findByIcon( QTreeWidget* aTreeWidget, const QIcon& aIcon, const int aColumn = 0 )
{
    QTreeWidgetItemIterator iterator( aTreeWidget );
    while ( *iterator )
    {
        if ( (*iterator)->data( aColumn, Qt::DecorationRole ) == aIcon )
        {
            return (*iterator);
        }
        ++iterator;
    }
    return nullptr;
}

This will find the first match only, is it enough ?

If not then here is a function which finds all the items with the given icon:

QList< QTreeWidgetItem* > findByIcon( QTreeWidget* aTreeWidget, const QIcon& aIcon, const int aColumn = 0 )
{
    QList< QTreeWidgetItem* > items;
    QTreeWidgetItemIterator iterator( aTreeWidget );
    while ( *iterator )
    {
        if ( (*iterator)->data( aColumn, Qt::DecorationRole ) == aIcon )
        {
            items << (*iterator);
        }
        ++iterator;
    }
    return items;
}
