QwtPlotCurve: wrong color and width when printing

[FelixB]

Hi,

I have some trouble printing a curve (on a real printer or into a pdf) with correct color and width. The on-screen-view is fine and so is the print preview too. I reproduced the problem with the bode example (win7, Qwt 5.2.1):

when I print the example "as it is", the yellow line is printed black. I can make it printing the correct color by changing

d_crv1->setPen(QPen(Qt::yellow));

d_crv1->setPen(QPen(Qt::yellow));

To copy to clipboard, switch view to plain text mode 

into

d_crv1->setPen(QPen(Qt::yellow,1));

d_crv1->setPen(QPen(Qt::yellow,1));

To copy to clipboard, switch view to plain text mode 

. The same applies to all pens: there must be an explicit width set to print the color.

but I can't change the width. changing the line into

d_crv1->setPen(QPen(Qt::yellow,10));

d_crv1->setPen(QPen(Qt::yellow,10));

To copy to clipboard, switch view to plain text mode 

makes the line thicker on screen (and also in print preview), but not in the printed result.

does anyone know whats wrong? Am I missing something?

thanks!
Felix

PS: the bode example does not have a print preview. I tested the preview-behaviour with my own project.

i have the same problem.
You can see your width = 10 only if you saves this plot as an image e.g. JPG
if you want also to print: load(image) and print(). I can see this width in my pdf file.
but not at runtime ...

Maybe fixed in Qwt 6.
