Rotating button

[dunbarx at aol.com]

Simulate it. Should be easy and fun.


Make a few buttons (not a field?) of the same rect that overlie each other. Each button has its own name or label. Button 1 is fully shown. The others all have their heights set to 0.



Take one button and in a repeat loop smoothly change its height from some value to zero in, say 2 seconds. At the same time, take another button and increase its value so that the height of the first is compensated by the height of the second. In other words, as btn 1 decreases from the top down, say, btn 2 increases from the top down.


You can do this with as many buttons as you wish, I should think, and at any rate.

What a control that would be!
I've seen what SVG graphics can do...I imagine it can be done in LIvecode,
although I haven't seen text displayed like you describe, it would seem
possible. Points is points.  but the math required...
