Datafield - detect default font size and color

You can get the background color for DF's:

bgColor=getBackgroundColor();

And based on that, set a fgColor (if bgColor is black, make the fgColor white, for example). (On devices I use, it's either white on black or black on white, and not sure about the edge devices)

As far as fonts, you can just figure out "what fits", and that could vary based on the DF you are running in. With a large DF (lets say 1 field), use a larger font than you would in a smaller (lets say 3 fields) sized DF .

The data field layout information used by the SimpleDataField is defined in {SDKROOT}/bin/devices.xml. The values should be very close to, or exactly the same as, what is used by the built-in data fields.

Thanks for the answers, I will look into that.

However, on a ride yesterday, I discovered that my Edge1000 is set to go automatically in nightcolors, and my datafield that I was testing, was not.

Isn't there a way to just let a datafield use systemcolors and behave like any other field?

If you are implementing SimpleDataField, or are using DataField.getBackgroundColor() (and setting the foreground color appropriately), it should do the right thing automatically.

As Travis said, with DataField.getBackgroundColor() on a regular DF, you should see it. When are you looking at that value?

onLayout(), etc may not work for this, so you may have to do it in onUpdate().
