[Paparazzi-devel] Cosmetic bug with the battery gauge

[Yves Touchette]

Hi,

I'm trying to resolve a small cosmetic bug with the width of the battery 
gauge in the strip.

I dont like the fact the the width of the battery gauge changes when the 
voltage goes from say 10V to 9V. There is a related issue where 10.0V gets 
displayed as 10.

I fixed this by replacing (in strip.ml):
strip.gauge#set_text (string_of_float value )
by
strip.gauge#set_text (Printf.sprinft "%5.01f" value)

This always display the decimal, but it fix the change of width from 
10.0->9.9. Presumably the font used isn't fixed width so the leading space 
int " 9.9" isn't as wide as "10.0". The only way I can think of is by pading 
the value with a leading 0.

strip.gauge#set_text (Printf.sprinft "%05.01f" value)


This would display 9.9V as 09.9. It's doesn't look perfect, but to me it 
looks better then the width of the gauge changing, espacially when the value 
oscillate between 10.0 and 9.9...

Another possibility is to get rid of the gauge and add the value in text 
somewhere else in the strip.

So let me know which solution you prefer and I'll make sure it gets added to 
the CVS.
