QLable::setText(text) is not showing the Text

[ranna]

HI,

I have an issue with QLable. I am creating the QLable object dynamically and after that i am adding it in a QTableWidget's cell (row x, colum 0);

Before adding the QLable into the TableWidget i am doing the following things.

{
QString lblNumber;
int nIndex = 0;
lblNumber.setNum(nIndex+1);
QLable *lblNo = new QLable(frame1);
lblNo->setAlignment(Qt::AlignCenter);
lblNo->setText(lblNumber);

tblwdgt->setCellWidget(row, 0, lblNo);
}

If i execute the application the lable's text is not visible to me.

Kindly help me to identify the actual root cause of this issue.

Thanks
Ranna

this code works fine for me

...
	QVBoxLayout *vb = new QVBoxLayout();
 
	QTableWidget *tv = new QTableWidget();	
	tv->setRowCount(10);
	tv->setColumnCount(10);
 
	for (int row = 0; row < tv->rowCount(); ++row) {
		for (int column = 0; column < tv->columnCount(); ++column) {
			QLabel *l = new QLabel();
			l->setAlignment(Qt::AlignCenter);
			l->setText("<b>Hello</b>");
			tv->setCellWidget(row, column, l);
		}
	}
 
	vb->addWidget(tv);
 
	setLayout(vb);
...

...
	QVBoxLayout *vb = new QVBoxLayout();

	QTableWidget *tv = new QTableWidget();	
	tv->setRowCount(10);
	tv->setColumnCount(10);

	for (int row = 0; row < tv->rowCount(); ++row) {
		for (int column = 0; column < tv->columnCount(); ++column) {
			QLabel *l = new QLabel();
			l->setAlignment(Qt::AlignCenter);
			l->setText("<b>Hello</b>");
			tv->setCellWidget(row, column, l);
		}
	}

	vb->addWidget(tv);

	setLayout(vb);
...

To copy to clipboard, switch view to plain text mode 

anyway, why do you use this approach?

What if you do this ?

{
int nIndex = 0;
 
// whatever you do with nIndex
// you incremented it by 1, we'll do the same
nIndex++;
 
QLable *lblNo = new QLable(frame1);
lblNo->setAlignment(Qt::AlignCenter);
lblNo->setText(QString::number(nIndex));
 
tblwdgt->setCellWidget(row, 0, lblNo);
}

{
int nIndex = 0;

// whatever you do with nIndex
// you incremented it by 1, we'll do the same
nIndex++;

QLable *lblNo = new QLable(frame1);
lblNo->setAlignment(Qt::AlignCenter);
lblNo->setText(QString::number(nIndex));

tblwdgt->setCellWidget(row, 0, lblNo);
}

I have tred the both solutions by adding the TableWidget in Layour and
lblNo->setText(QString::number(nIndex)); But it is not working and still i am facing the same problem.

ok, could you attach compilable example which represent this issue?
