Hi Tom,

Here is still another solution - somewhat different from yours in "Buttons.rev" - based on the recommendations of the stack "grafikbuttons" we put on our ftp-server for our students.

Put the "Bdown" image *on top* of the "BUp" image. Hide the "BDown" image.
Put the script to toggle between up and down into the "BUp" image, i.e. show and hide the "BDown" image 
from there, in this way there is no problem with receiving the "mousedown" and "Mouseup" messages.
As your "BDown" and "BUp" images are of different size you have to adjust - make smaller - the rect of the 
underlying "BUp" image when you show the "BDown" image on top of it.

Sample script for the "BUp" image (I had renamed the images to "top.png" and "base.png"):

Local OldRect, NewRect
on mousedown
 put the rect of me into OldRect
 put OldRect into NewRect
 add 4 to item 1 of NewRect
 add 4 to item 2 of NewRect
 set the rect of me to NewRect
 show image "base.png"
end mousedown
on mouseUp
 set the rect of me to OldRect
 hide image "base.png"
end mouseUp

There remains your "airplane.gif". Put a button with the airplane as the icon on top of the two images. Uncheck all checkboxes of tab "Behavior" and "Appearance".

Put the following script into this button:

on mousedown
 move me relative 2,2
 send mousedown to image "top.png"
end mousedown
on mouseUp
 move me relative -2,-2
 send "Mouseup" to image "top.png"
end mouseUp

Group the three controls.

The movement of this group is much smoother than of the groups in your stack "buttons.rev".--

Thanks to Chipp Walters, there is his "ButtonGadget" that addresses related, but different issues. I use his tool relatively often and additionally design my own png-images with the very affordable tool "RealDrawPro" (www.mediachance.com).

For some of my applications I would appreciate a new feature that makes it possible to place button names/labels directly *on* an icon, not just right, left, or below. Thus it would be possible to use custom buttons whose labels could be changed during runtime (this is of course not possible with the ButtonGadget stack); e.g. language learning exercises where the labels of the custom buttons change with each new problem could benefit from such a feature.

Of course you could also set the backpatterns of buttons to the custom images and then have the labels directly on top. But this solution is viable only in case of rectangular images, as with non-rectangular images the transparent parts of the PNGs appear as black.

Wilhelm Sanke
