How to delete all rows from QTableWidget

Question

I am trying to delete all rows from a QTableWidget . Here is what I tried.

for ( int i = 0; i < mTestTable->rowCount(); ++i )
{
    mTestTable->removeRo         


        

Answer 1

Your code does not delete last row.

Try this one.

int totalRow = mTestTable->rowCount();
for ( int i = 0; i < totalRow ; ++i )
{
       mTestTable->removeRow(i);
}

In your code, on the first time, rowCount() have value 2 and value of the i is 0, so its delete 1st row,

But on the second time value of i incremented with 1, but rowCount() return the updated row count which is now 1, so, it does not delete the last row.

Hope now you ll be clear.
