set ItemDelegate for QTableWidget(s) in QTabWidget(s)

[srazi]

Myapp has a QTabWidget, and every Tab has a QTableWidget.
I try to set MyItemDelegate on every table.

When I use following code:

for (int i = 0; i < mainTabWidget->count(); ++i)
{
	CurrentTabWidget *tmp = getCurrentTabWidget(i);
	QAbstractItemDelegate *tmpDelegate = tmp->table->itemDelegate();
	if (tmpDelegate)
	{
		delete tmpDelegate;
		tmpDelegate = 0;
	}
	tmp->table->setItemDelegate(new MyItemDelegate(CurrentTabWidget->table));
}

for (int i = 0; i < mainTabWidget->count(); ++i)
{
	CurrentTabWidget *tmp = getCurrentTabWidget(i);
	QAbstractItemDelegate *tmpDelegate = tmp->table->itemDelegate();
	if (tmpDelegate)
	{
		delete tmpDelegate;
		tmpDelegate = 0;
	}
	tmp->table->setItemDelegate(new MyItemDelegate(CurrentTabWidget->table));
}

MyItemDelegate is set on every Tab, but for exampe:
if I open three tab and select second one and then close first then second one, I see current Tab (third one) has no itemDelegate (its items aren't painted)
what's wrong with this code?

The following code works perfectly:

int currentIndex = mainTabWidget->currentIndex();
for (int i = 0; i < mainTabWidget->count(); ++i)
{
	mainTabWidget->setCurrentIndex(i);
        //currentTab is a pointer to CurrentTabWidget within QTabWidget current Tab
	QAbstractItemDelegate *tmpDelegate = currentTab->table->itemDelegate();
	if (tmpDelegate)
	{
		delete tmpDelegate;
		tmpDelegate = 0;
	}
	currentTab->table->setItemDelegate(new MyItemDelegate(currentTab->table));
}
mainTabWidget->setCurrentIndex(currentIndex);

int currentIndex = mainTabWidget->currentIndex();
for (int i = 0; i < mainTabWidget->count(); ++i)
{
	mainTabWidget->setCurrentIndex(i);
        //currentTab is a pointer to CurrentTabWidget within QTabWidget current Tab
	QAbstractItemDelegate *tmpDelegate = currentTab->table->itemDelegate();
	if (tmpDelegate)
	{
		delete tmpDelegate;
		tmpDelegate = 0;
	}
	currentTab->table->setItemDelegate(new MyItemDelegate(currentTab->table));
}
mainTabWidget->setCurrentIndex(currentIndex);

At line 10 of first code block, what is "CurrentTabWidget->table"?
