I'm not sure about the rest of you, but I for one am going to read the
change log!

People shoud really, really read Changelog! 

REALLY!

Now by default Gambas ignores the DPI of the screen returned by X-Window
when 
deciding the size of the font. Of course this is a bad thing, but this way 
gambas application fonts looks everywhere the same.

For example, when you decide that your Label has a font size of 18, you want

implicitely that on every Linux box, the user gets the same size. Because 
when you draw your interface visually, you think actually "pixels" and not 
"points", that is a resolution-dependent unit.

Note that the value of DPI returned by X is sometimes not accurate, and so, 
sometimes, when you install a Mandrake, you have small fonts or big fonts 
with the same screen, according to your video card!

To change the Gambas behaviour , you have a Font.Resolution property and a 
Desktop.Resolution property. By default, Font.Resolution = 96 whatever 
Desktop.Resolution is.

It is the same thing in Windows - maybe a proof that it is a bad thing :-)

You can change the value of Font.Resolution if you need. If you want the old

Gambas behaviour, try Font.Resolution = Screen.Resolution at the start of 
your program.

As you noticed, Font.Resolution is not used for printing. Happily!
Otherwise, 
a 10 pt font on the screen would become a 10 * 600 / 96 = 62.5 pt font on
the 
printer!

I hope everything is clear now.

P.S. Did I mention that everybody should read the ChangeLog ?
