Basic Qprinter question
Message 1 in thread
Thank you for reading this.
I'm trying to print out a 12 x 12 matrix of QChars using the default
settings of the printer and QPrinter, nothing fancy at this stage.
The matrix prints as a black 6mm block so I have simplified what I'm trying
to
achieve by replacing the matrix with a string.
Instead of printing "test" on two separate lines I seem to be getting the
word over typed twice on the same spot on the page. I have looked at several
Qt example files and taken what I think I need.
Can someone point out what I'm doing wrong?
void wordsearch::print()
{
if (printer->setup(this))
{
QPainter paint;
if(!paint.begin(printer))
return;
for(int row = 0; row < 2; row++)
paint.drawText(0, row + 150, "test");
}
}
Regards,
Phil.

Looks ok for me. Maybe a problem with your setup? You could try to set
your print parameters manually (printer->setPagesize(...),
printer->setResolution(...), etc.). Just to see if it makes a
difference.

Surely you meant to write this:
paint.drawText(0, row * 150, "test");

Thank you Guido and David for your replies. I don't know why I didn't see
that myself. By the way, *20 works well.
Now I have another related problem that I will post in a separate message
(Calling a function from a dialog window).
Regards,
Phil.

Easy. It was syntactically correct code. So it did not stuck out and
most people just 'translate' it to the correct meaning in the head.
Especially the original coder.
I really wish there was some coding technique, which helps to prevent
such sort of mistakes.
