Font used in gadgets?

What determines the font used to display the text on gadgets?

For example, if I type in this code:

StartButton = CreateButton("Start", 100, 0, 100, 40, window) 

what determines the font used to write the word "Start"?

Can it be changed? Is it dependent on the OS?

Will it ever change?

Thanks for clearing that up. Now what font (and size) is the standard font used if no font is loaded?

Whatever the user has set in their Windows settings?

Any other guesses? :)

Microsoft Sans Serif 8?

Trebuchet MS 10 or Tahoma 8
