QSortFilterProxyModel -filterAcceptsRow()- filter parent Node and child Node

[andre]

Sounds like you forgot to add the .h file to your HEADERS section in your .pro file, and the .cpp file to the SOURCES section?

What does _parent type in this string?
@bool filterAcceptsRow(int source_row, const QModelIndex &source;_parent) const;@
And wath does this argument do?
And second question:
source_parent is source->parent()?
And in advance sorry for stupid questions)

There was an unfortunate bug at the time in DevNet, that sometimes inserted ; at the wrong places in code sections. The code listing I posted suffered from this. The argument is supposed to be a single argument source_parent. I'll try to fixup the original posting. Thanks for noticing.

[Ruzik]

It is clear.
One more thank you for your help!

Esta implementación recorre todo los sub-Nodos del padre buscando que el filterRegExp coincida con el Qt::DisplayRole del sub-Nodo.

El algoritmo no utiliza recursividad :D

@bool SortFilterProxyModel::filterAcceptsRow(int source_row, const QModelIndex &source_parent) const
{
QList<QModelIndex> children;
children << sourceModel()->index(source_row, 0, source_parent);

bool show = false;
for(int i = 0; i < children.length(); i++)
{
    if(show) break;

    // Add sub Nodos
    //
    for(int c = 0; c < sourceModel()->rowCount(children[i]) ;c++)
        children.append(children[i].child(c,0));

    QString type = sourceModel()->data(children[i], Qt::DisplayRole).toString();
    show = type.contains(filterRegExp());        
}
return show;
