Font Selection Advice for GUI Linux supporting different resolutions.

[nbkhwjm]

I have an application that looks perfect on my development system, which is a laptop with screen resolution of 1024x768, running ubuntu 8.04. If i run my application on a system with the same resolution it looks fine

When i run it on a system with something like 1600x1200 resolution again ubuntu 8.04, the fonts look MASSIVE, way too large.

I felt this was a font selection issue, so i made sure i selected a font that would be on most systems "Helvetica". I since have seen that the proper font is being chosen, although it obviously doesnt look like it.

in main.cpp i have this to check.

QFont font( "Helvetica", 10 );
     app.setFont( font );
 
         QFontInfo info(font);
         QString family = info.family();
	qDebug() << "FONT:" << family;
    	qDebug( "Font size requested is    : %d", font.pointSize() );
    	qDebug( "Font size actually used is: %d", info.pointSize() );

QFont font( "Helvetica", 10 );
     app.setFont( font );

         QFontInfo info(font);
         QString family = info.family();
	qDebug() << "FONT:" << family;
    	qDebug( "Font size requested is    : %d", font.pointSize() );
    	qDebug( "Font size actually used is: %d", info.pointSize() );

To copy to clipboard, switch view to plain text mode 

On my development system i get this in the console:
FONT: "Helvetica"
Font size requested is : 10
Font size actually used is: 11

on the other system (the one with the 1600x1200 screen resolution) I get this:
FONT: "Helvetica"
Font size requested is : 10
Font size actually used is: 9

So they should both be comparable, but they are not.

Any advice is appreciated, thanks
