Some questions about the button widget

Hi all,

Have some questions.

I define a new button like so :

&nbsp; &nbsp; local buttonAnswerThree = widget.newButton &nbsp; &nbsp; { &nbsp; &nbsp; &nbsp; &nbsp; parent = sceneGroup, &nbsp; &nbsp; &nbsp; &nbsp; defaultFile = "buttonAnswer.png", &nbsp; &nbsp; &nbsp; &nbsp; overFile = "buttonAnswer.png", &nbsp; &nbsp; &nbsp; &nbsp; label = "ANSWER THREE", &nbsp; &nbsp; &nbsp; &nbsp; --emboss = true, &nbsp; &nbsp; &nbsp; &nbsp; --font = "Sans Poster Bold JL", &nbsp; &nbsp; &nbsp; &nbsp; labelColor = { default = { 130, 82, 42 }, over = { 163, 25, 12} } &nbsp; &nbsp; &nbsp; &nbsp; --onRelease = buttonAnswerOnePressed, &nbsp; &nbsp; }

The label color however, does not seem to be working properly.

As soon as one of the r,g,b values have a value > 0, they seem to become 255.

e.g. {1,0,0} , the label will be completely red.

Am I doing something wrong here ?

Also, if i want to build for android, how would I go about changing the fonts for the label.

If i define it like the above ( pointing to a system font in windows ), there will be an error when building for android.

Thanks in advance!

Starting sometime a couple of years ago, we moves away from 0…255 for color ranges and changed from 0…1, where 0 is no color, 1 is 100% of the color. If you want a medium red, you would use { 0.5, 0, 0 }. If you have your colors in a 0…255 range, simply divide by 255 to get their fractional value:

default = { 130 / 255, 82 / 255, 42 / 255 }

Thanks for the reply.

Most of the examples on the web were still using 255, I guess that was what was confusing me.

As for the second part of my question i found the answer here :

Thanks again
