Adding dynamically a row in a QTableWidget - c++

Question

I must adding a row in a QTableWidget. Previously I add all rows with a size of a list, like this:
MyProgram::MyProgram( QWidget* parent )
: QDialog( parent )
, ui( new Ui::MyProgram )
{
ui->setupUi( this );
QStringList allFiles = QDir( "~/" ).entryList( QStringList << "*.txt" );
ui->myQTableWidget->setRowCount( allFiles.size() );
for( int cont = 0; cont < allFiles.size(); ++cont )
{
//insert values in my QTableWidget
}
}
But now I can't know how many files I will show in QTableWidget, because I added a validation before. It like this:
MyProgram::MyProgram( QWidget* parent )
: QDialog( parent )
, ui( new Ui::MyProgram )
{
ui->setupUi( this );
QStringList allFiles = QDir( "~/" ).entryList( QStringList << "*.txt" );
for( int cont = 0; cont < allFiles.size(); ++cont )
{
bool ok = true;
try {
//try something
} catch( //exception )
{
ok = false;
}
if (ok) {
//insert values in my QTableWidget
}
}
}
How I can add a row in a QTableWidget without knowing how many items this will have?

This works:
MyProgram::MyProgram( QWidget* parent )
: QDialog( parent )
, ui( new Ui::MyProgram )
{
ui->setupUi( this );
QStringList allFiles = QDir( "~/" ).entryList( QStringList << "*.txt" );
for( int cont = 0; cont < allFiles.size(); ++cont )
{
bool ok = true;
try {
//try something
} catch( //exception )
{
ok = false;
}
if (ok) {
int row = ui->myQTableWidget->rowCount();
ui->myQTableWidget->insertRow( row );
// setItems
}
}
}
