QGraphicsTextItem in a Widget ,Is it Possible ??

[salmanmanekia]

Hi,
I have written this code in my class derived from QWidget,but it shows no text ..!!

class ProgressWidget:public QWidget
{
..
QGraphicsTextItem *txt1;
..
};

class ProgressWidget:public QWidget
{
..
QGraphicsTextItem *txt1;
..
};

To copy to clipboard, switch view to plain text mode 

void ProgressWidget::instructionStringOne()
 {
	 txt1->setPlainText(str1);
	 txt1->setFont(fontStr1);
	 txt1->setTextWidth(TEXT_WIDTH);
	 txt1->setPos(INSTRUCTION_TEXT_1_X,INSTRUCTION_TEXT_1_Y);
	 txt1->show();
 
 }

void ProgressWidget::instructionStringOne()
 {
	 txt1->setPlainText(str1);
	 txt1->setFont(fontStr1);
	 txt1->setTextWidth(TEXT_WIDTH);
	 txt1->setPos(INSTRUCTION_TEXT_1_X,INSTRUCTION_TEXT_1_Y);
	 txt1->show();
	 
 }

To copy to clipboard, switch view to plain text mode
