QTextDocument - line spacing

[mazurekwrc]

Hi, I use QGraphicsTextItem to show QTextDocument by using setDocument function, could you tell how to change line spacing, because i need to decrease it.

You could use setHtml with modified CSS line-height attribute. Or have a look if rtf has a similar option. (Or whatever you have in your QTextDocument. Sorry but my crystal ball is still in repair...)

line-height attribute isn't supported by Qt
http://doc.trolltech.com/4.5/stylesheet-reference.html#list-of-properties
so I can't do it by this way...

Jepp, sorry, I was misreading the information under QTextDocument::defaultStyleSheet
The style sheet needs to be compliant to CSS 2.1 syntax.
Since only the syntax is meant, you have to go the harder way using QTextLayout yourself. You might want have a look at http://doc.trolltech.com/qq/qq24-textlayouts.html.

Is there a posibility to adjust the line spacing in the font metrics?
I use ttf font with Qt 4.5 on a linux system.

Thanks for help

I use QGraphicsTextItem with Qt4.5. As act of desperation I changed font properties of true type font with help of fontforge.

hhead ascent offset
hhead descent offset
hhead line gap

It works.
