[Qt-interest] Making a table in a form the same width as the tab within which the form is placed

[Robert Wood]

In case anyone else comes across this, it turns out it's not that 
difficult to do once I'd actually sussed out the command.

1. Create the new tab.

	tabCount = mainTab->count();
	qwVector.insert(tabCount,newTab);
	mainTab->addTab(qwVector[tabCount],tabName);
	mainTab->setCurrentIndex(tabCount);

2. Create a QHBoxLayout and attach it to the tab:

	quint8 i = (mainTab->count() - 1);
	QHBoxLayout *hBLO;
	hBLO = new QHBoxLayout(qwVector[i]);

3. Once the new widget has been chosen, stick it in the QHBoxLayout. For 
example:

	table_contents *ein = new table_contents(qwVector[i],&db);
	hBLO->addWidget(ein);
	ein->show();

This does exactly what I want. The important thing was the QHBoxLayout.
