table not getting created completely.

ashajg

Hi

I have written a code for creating table. but when I am running that code, some times table is not getting created(only headers are visible ) and some times it works perfectly. This problem is more persistent on embedded board (IMX6) than windows and I am not getting any error.

I am filling my model with data==>
main.cpp

ServiceLogTableModel *t1 = ServiceLogTableModel::getStaticInstance();//Model
 t1->addInitialData();
QSortFilterProxyModel  *proxyModel =t1 ->getProxyModelInstance();
 proxyModel->setSourceModel(t1);
 proxyModel->setSortRole(ServiceLogTableModel::TableDataRole);
 proxyModel->setFilterRole(ServiceLogTableModel::TableDataRole);

how can I solve this issue so that table should get completely created?
