[QT4] Printing a dialog

[KShots]

Your call to grabWidget() should be grabWidget(T, T->rect());

Yeah, that makes a lot more sense

Also, drop the setViewport() and setWindow() stuff.

Done.

Thus far, nothing is yet changing

To re-iterate, this is what I have now:

void formMainApp::menuFilePrint()
{
   QPrinter p;
   p.setColorMode(QPrinter::GrayScale);
   //No reason for color in this dialog
   p.setCreator("TIRdb");
   p.setDocName("TIRdb Printout");
   QPrintDialog qp(&p, this);
   if(qp.exec() == QDialog::Accepted)
   {
      QModelIndexList MIL = ui.treeViewSQLList->selectionModel()->selectedIndexes();
      QPainter painter;
      for(QList<QModelIndex>::iterator i = MIL.begin(); i != MIL.end(); ++i)
      {
         formTIR * T = TIRTree->findTIR(*i);   //TIRTree is my model, findTIR returns the dialog
         if(!T)   //Some elements in the tree do not have dialogs attached to them
         {
            continue;
         }
 
         QPixmap qpm = QPixmap::grabWidget(T, T->rect());
         if(qpm.isNull())
         {
            qDebug() << "Failed to capture the dialog for printing";
            return;
         }
 
         qpm.scaled(p.pageRect().width(), p.pageRect().height(), Qt::KeepAspectRatio);
 
         painter.begin(&p);
         painter.drawPixmap(0, 0, qpm);
         painter.end();
      }
   }
}

void formMainApp::menuFilePrint()
{
   QPrinter p;
   p.setColorMode(QPrinter::GrayScale);
   //No reason for color in this dialog
   p.setCreator("TIRdb");
   p.setDocName("TIRdb Printout");
   QPrintDialog qp(&p, this);
   if(qp.exec() == QDialog::Accepted)
   {
      QModelIndexList MIL = ui.treeViewSQLList->selectionModel()->selectedIndexes();
      QPainter painter;
      for(QList<QModelIndex>::iterator i = MIL.begin(); i != MIL.end(); ++i)
      {
         formTIR * T = TIRTree->findTIR(*i);   //TIRTree is my model, findTIR returns the dialog
         if(!T)   //Some elements in the tree do not have dialogs attached to them
         {
            continue;
         }

         QPixmap qpm = QPixmap::grabWidget(T, T->rect());
         if(qpm.isNull())
         {
            qDebug() << "Failed to capture the dialog for printing";
            return;
         }

         qpm.scaled(p.pageRect().width(), p.pageRect().height(), Qt::KeepAspectRatio);

         painter.begin(&p);
         painter.drawPixmap(0, 0, qpm);
         painter.end();
      }
   }
}
