We looking at very simple button design:
1) Border color is on/white/2px
2) background is set to clear (no color assignment and no icon)
3) background opacity set to 50% # if we can figure out how....
4) Button name/label white
Now... I realize that if # 2 above is true, then possibly, since there are no
pixels at all in the background that the algorithm might not be possible from a
video card point of view... so we *could* set the background to white and set
the opacity to a grayscale?transparency value of say... 50% but the idea is
that the text of the button name/label remains fully, 100% opaque, even thought
background has an alpha channel value (some level of transparency)
From my fiddling... (I could be missing something) this is not possible either
with buttons of fields or graphics.
The use case is, again, as discussed in another thread: we want visibility of
the text on top of *any* image to be visible. We do this in print all the
time... but we cannot separate the blending of the text label or text itself
and the background of a button/field in LC... at least I have not found a way.
Um, well, at the risk of annoying you somewhat . . .
I have almost always "rolled my own" buttons just because of the
limitations on Livecode-native
buttons.
I use GIMP with a series of layers (nothing particularly original or
difficult there): one for the
'button' (rectangle with rounded edges), one for the image, and one for
the label. Then one can
fiddle around with levels of transparency as much as one likes.

Would be grateful if you could clarify this.
