Memory Management while Inserting and Removing values from QTableView

In my Application I am required to insert and remove data from tableView multiple times while application is running.After a complete cycle of Inserting and removing data from tableView memory(RAM) consumption of my application increases as checked in task Manager. After each successive cycle of insertion and deletion memory consumption keeps on Increasing.



Below is my code:

}


Memory consumption From app start:



11020 KB when app started



16144 KB when display data function Called



12812 KB when clear model called



16356 KB when display data function Called



13304 KB when clear Model Called


So Ram consumption increased by 2 MB in 2 Insert/Remove cycles.



To me it seems to be memory leak issue because memory is allocated to QStandardItem object( item = new QStandardItem(QString("%0").arg(value))) but is never freed.I tried to free the memory by calling delete item but after it a row is inserted with blank column.



What might be the possible reason for increase in memory consumption.
