Hi All,

Hi All,

My Requirement is Print table , Means Generating .ps file and giving to APS Print but I have some issues.

1) Preview is not visible on APS Print

2) Printing table but ignoring some rows

3) Grid lines are not Printing

my code is :

void TableEditor::printt()
{
 
QPrinter printer(QPrinter::HighResolution);
//printer.setFullPage(true);
//printer.setPageSize(QPrinter::A4);
/*int rightMargin = printer.paperRect().right() - printer.pageRect().right();
 int bottomMargin = printer.paperRect().bottom() - printer.pageRect().bottom();
int leftMargin = printer.paperRect().left() - printer.pageRect().left();
int topMargin = printer.paperRect().top() - printer.pageRect().top();*/ //This is commented
//printer.margins(&topMargin,&leftMargin,&bottomMargin, &rightMargin);
 
printer.setOutputFileName("rtest.ps");
QPrintDialog dlg(&printer, this);
double totalWidth = 0.0;
double totalHeight = 0.0;
double totalPageHeight=0.0;
//QRect area;
if (dlg.exec() == QDialog::Accepted){
 const int rows=view->model()->rowCount();    
const int cols = view->model()->columnCount(); 
printf("no of rows\n %d",rows); 
printf("\n no of columns %d",cols);  
for (int c = 0; c < cols; ++c) { 
       totalWidth += view->columnWidth(c);    }    
for(int p=0; p<45; p++)   //45
{
totalPageHeight+= view->rowHeight(p);
 
 
}
for (int r = 0; r < rows; ++r)   
 {        totalHeight += view->rowHeight(r);    }
 
 
}  //if loop ending here
 
QPainter painter(&printer);
//QPainter::setRedirected(view->viewport(), &painter);    
//QPaintEvent event(QRect(0, 0, totalWidth, totalHeight));
//view->paintEvent(&event); 
//painter.drawLines(0,0,rows,cols);  
//QApplication::sendEvent(view->viewport(), &event);    
//QPainter::restoreRedirected(view->viewport());   //This is commented for testing row nums
//QPainter painter(&printer);
painter.begin(&printer);
const int rows=view->model()->rowCount();
const int columns=view->model()->columnCount();
printf("The num of rows are %d",rows);
QRect area = printer.paperRect(); // here should be pageRect
const double xscale = area.width() / totalWidth;        
const double yscale = area.height() / totalHeight;         
const double pscale = area.height() / totalPageHeight;        
 painter.scale(xscale+9, yscale+9);   // With the scaling 3 It is Printing all   
//painter.translate(area.x() + xscale, area.y() + pscale);  //This is original
painter.translate(area.x() + xscale, area.y() + yscale);        
//painter.save(); //commented
 int x=0;
 //int y=0 ;// This is introduced for the columns
//view->paintEvent(&event);
QPainter paint(this);
paint.setPen(Qt::red);
 paint.drawRect(0, 0, 0, 0);
