Hello,

	I am facing a problem with QTable.What i need is to block all the
entries to the QTable except numericals.That is to prevent entering
alphabets in the cells of QTable.

Thanks in advance
Sajeesh

My guess is that you have to subclass QTableItem, override createEditor
and install an validator for that editor. Something like:

QWidget* YourTableItem::createEditor(){
	QLineEdit *le = new QLineEdit(table()->viewport());
	QDoubleValidator *dv = new QDoubleValidator(le);
	le->setValidator(dv);
	return le;
} 

Take a look at the docs for QTableItem and QDoubleValidator for
more info...
