Great Idea!

A further improvement comes to my mind: give different areas of the bar
different colors? (say: 0-50% green, 51-80% yellow, 81-100% red)

I have no idea how to implement this in a clean (and understandable :-)
way...

maybe a bar could have a 'background image', and the bar drawing
function just does alpha blending?

Another great idea, which I already improved: I removed all the BOLD
stuff (sorry, Till :-) an re-added this as a text-widget specific
attribute. So you can add a "style 'bold'" attribute to every text
widget. This attribute is dynamically evaluated, so you can even change
between bold and normal font during operation (there's an example in the
lcd4linux.conf.sample from current CVS,  using the test::onoff() plugin.
Have a look at the CPU widget)

While implementing this, I found the current widget attribute handling
to be quite complex. So I tried to hide some of the complexity a bit in
the new 'dynamic property' functions. Some properties of the text widget
(namely prefix postfix and style) use this new stuff. Looks much cleaner
to me....


btw, there's a 'truetype' widget for graphic displays on my wishlist....


bye, Michael
