QComboBox of check boxes not rendering check boxes on linux but works properly on windows

[Zetsil]

I have the following function that creates a QComboBox of checkboxes :

this->Model = new QStandardItemModel;

   for(int i=0;i<SLIderbars->size();i++){
     this->Item1 = new QStandardItem;
     this->Item1->setText(m_sliderNames->itemText(i));
     this->Item1->setFlags(Qt::ItemIsUserCheckable | Qt::ItemIsEnabled);
     this->Item1->setData(Qt::Unchecked, Qt::CheckStateRole);




     this->Model->insertRow(i, this->Item1);


     this->Items.push_back(this->Item1);
    }
   connect(this->Model, SIGNAL(dataChanged ( const QModelIndex&, const QModelIndex&)), this, SLOT(slot_changed(const QModelIndex&, const QModelIndex&)));

     this->comboBox->setModel(this->Model);

The code works how it supposed to work on windows but when I try to compile it on Linux the checkboxes are not visible.

Can someone help me make the checkboxes render on Linux version?

@Zetsil said in QComboBox of check boxes not rendering check boxes on linux but works properly on windows:

SLIderbars->size()

What does it return on Linux?

[Zetsil]

@jsulm The drop-down list is created dynamically after the size of how many slider bars(that work as a video player slider ) are .So it returns the size correctly.

Did you really check that?
Like

    qDebug() << SLIderbars->size(); 
    for(int i=0;i<SLIderbars->size();i++){
