[Qt-interest] Tree Item view Highlighter

[Sajjad]

Hello forum,


The following topic is the follow-up which has been discussed several days
ago. I want to highlight a particular tree item based on pattern matching.
In  that case i have sub-classed the QSortFilterProxyModel and over-ridden
the following function


//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

bool H3DHighlighterProxyModel::filterAcceptsRow(int source_row, const
QModelIndex &source_parent) const

{

    std::cout << "In the filtration" << std::endl;

     QColor highLighter = Qt::cyan;

    QColor noHighLighter = Qt::white;

     if(sourceModel()->data(source_parent).toString().contains(filterRegExp()))

    {

        std::cout << "Will be highlighted" << std::endl;

        sourceModel()->setData(source_parent,QVariant(highLighter),Qt::BackgroundRole);

    }

    else

    {

        std::cout << "Will not be highlighted" << std::endl;

        sourceModel()->setData(source_parent,QVariant(noHighLighter),Qt::BackgroundRole);

    }

     return true;

}




///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////


But i am not getting any high-lighting effect with the textChanged signal in
the line edit . The appropriate slot has been connected as follows:



//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

  void H3DNodeListWidget::highlightRegExpChanged()

{

    QRegExp regExp(m_nodeHighlightingEditor->text(),Qt::CaseInsensitive);

     m_highlightModel->setFilterRegExp(regExp);

}



////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////


If there is anything missing in the process or logical mistake, please mark
it out for me that i am missing.



Regards
Sajjad
