QPainter & QPrinter

[MrLibya]

Hello
The software that I'm making is POS , so now i got litile problem with the printer
I want make the QPainter draw text on the center , but the problem is with the points ( it will have different point with different paper size)

int height = printer->heightMM();
    int width = printer->widthMM();
    QPainter painter(printer); // create a painter which will paint 'on printer'.
    painter.setPen(Qt::blue);
    painter.setFont(QFont("Tahoma",16));
    painter.drawText(QPoint(height +130, width),ConfigDialog::_shopName);

So this code wont really help , so how i can make it draw text on the top middle , so how i do it ?

Use drawText() overload that uses a rectangle, not point and specify alignment in that rectangle to be top and centered horizontally:

int height = printer.height();
int width = printer.width();

painter.setPen(Qt::blue);
painter.setFont(QFont("Tahoma",16));
painter.drawText(QRect(0, 0, width, height), Qt::AlignTop | Qt::AlignHCenter, ConfigDialog::_shopName);
