QTableWidget

[A Former User]

Sometimes, when I try to decrease my TableWidget size, my program stops with an error in the second line line:
@
table->setColumnCount(size);
table->setRowCount(size);
@

When the last size is bigger then then new one, program do it correctly, without any mistakes.

all my function:
@
void MainWindow::setSize(int size) {
int lastSize = table->rowCount();

table->setColumnCount(size);
table->setRowCount(size);

if (size > lastSize) {
    table->setColumnWidth(size-1, table->rowHeight(1));
    QTableWidgetItem *item = new QTableWidgetItem(tr("x%1").arg(size));
    table->setHorizontalHeaderItem(size-1, item);
    table->setVerticalHeaderItem(size-1, item);
}

}
