PaintEvent() in a dynamically created and destroyed objet not working.

[savaliya_ambani]

hi,

i am trying to set transparency using QPainter:aintEvent(QPaintEvent *event), for dynamic widget which is created and destroyed at run time .

My code is like this:

DynamicWidget::DynamicWidget(QSignalMapper *lsig, QWidget *parent)
{
   widget =new QWidget();
   widget.setGeoMetry(0,0,480,800);
 
  label1=new QLabel(widget);
  label2=new QLabel(widget);
  label3=new QLabel(widget);
  line1=new QLineEdit(widget);
 
  //Rotate widget using QGraphicsView and QGraphicsScene
  widget.setParent(this);
  //embedding widget into a view and scene
  view.show();
}
 
 DynamicWidget::paintEvent(QPaintEvent *event)
{
  qDebug("paint event occured");
  QPainter painter(this);
  //Draw rectangle of GeoMetry(0,0,480,800)
  //setOpacity(0.5);
}
 
 
 DynamicWidget::~DynamicWidget()
{
 delete label1;
 delete label2;
 delete label3;
 delete line1; 
 delete  view;
 delete scene;
 
 delete widget;
 
 }

DynamicWidget::DynamicWidget(QSignalMapper *lsig, QWidget *parent)
{
   widget =new QWidget();
   widget.setGeoMetry(0,0,480,800);

  label1=new QLabel(widget);
  label2=new QLabel(widget);
  label3=new QLabel(widget);
  line1=new QLineEdit(widget);

  //Rotate widget using QGraphicsView and QGraphicsScene
  widget.setParent(this);
  //embedding widget into a view and scene
  view.show();
}

 DynamicWidget::paintEvent(QPaintEvent *event)
{
  qDebug("paint event occured");
  QPainter painter(this);
  //Draw rectangle of GeoMetry(0,0,480,800)
  //setOpacity(0.5);
}


 DynamicWidget::~DynamicWidget()
{
 delete label1;
 delete label2;
 delete label3;
 delete line1; 
 delete  view;
 delete scene;

 delete widget;

 }

To copy to clipboard, switch view to plain text mode 

/*****************End******************/

Code gets compiled and when i run ,i can see DynamicsWidget once when the DynamicsWidget created, and later on it not showing anything.

I am delete DynamicsWidget at the interval of 3 seconds. Can't i take QPainter painter(this), no.of times. This is working nicely on Static object for other classes.

what could be the problem?
