[SOLVED]Doesn't QTableWidgetItems create memory leaks
-
We usually add items to QTableWidget in this manner
@QTableWidgetItem *item0 = new QTableWidgetItem();
QTableWidgetItem *item1 = new QTableWidgetItem();
ui->tableWidget->setItem(m, 0, item0);
ui->tableWidget->setItem(m, 1, item1);
item0->setText("entry1");
item1->setText("entry2");@Now, if suppose we clear the table
@ui->tableWidget->clearContents();@
And again execute the code for displaying entry, new items will be created for displaying. Creating memory leaks, as there we did not delete the item1 and item2 -
If you actually look at the implementation file of "qtablewidget.cpp":http://qt.gitorious.org/qt/qt/blobs/4.7/src/gui/itemviews/qtablewidget.cpp
it actually deletes the items.
@void QTableModel::clearContents()
{
for (int i = 0; i < tableItems.count(); ++i) {
if (tableItems.at(i)) {
tableItems.at(i)->view = 0;
delete tableItems.at(i);
tableItems[i] = 0;
}} reset();} @
