I have not tried this at home.

But in experimenting with a simple gadget to help a new user, I made two largish square buttons, and set the backColor of btn 2 to any old color. I put this into the card script:

Code: Select all

on mouseMove
   get the rect of btn 1
   put the mouseV into item 2 of it
   if the mouseloc is within the rect of btn 1 and the mouse is down then set the rect of btn 2 to it
end mouseMove

Not rocket science, button 2 "fills" or "empties" btn 1. But the when I move the cursor in a downward direction, the backcolor of btn 2 changes to dark purple. It displays the prescribed color just fine on the way up. If I clear the color of btn 2, same thing, basically, clear going up, purple going down.. If I start with two brand new rectangular buttons, not setting any color, there is no such effect. As soon as I set any backColor in btn 2, though, this odd effect appears.

I tried

Code: Select all

on mouseEnter
 set the backColor of btn 2 to "113,115,23" --arbitrary
end mouseEnter

on mouseMove
   get the rect of btn 1
   put the mouseV into item 2 of it
   if the mouseloc is within the rect of btn 1 and the mouse is down then
      put the backColor of btn 2 --to monitor while moving
      set the rect of btn 2 to it
   end if
end mouseMove

The initital setting ("113,115,23") is shown in msg going both up and down, and LC seems not to know about it. The purple "down" color seems to be overlaid on, not substituted for, the initial color. This can be seen if you try different starting colors. The purple "down" overlay mixes differently with any initial color choice.

Seems like a bug to me, and an odd one at that. LC 6.03, Mac OS 10.5.8

I'm not seeing that here.
Win 7 liveCode 6.1.2

Nice solution to the question.

Wait... I do see a boarder disappearing along the bottom on the down motion not the up > When btn 2 is click on, not when btn 1 is clicked on.

Simon.

Tried this at home. OSX 10.6.8, LC 6.1.3 Same weirdness.

Now if I do not reference that vary same button to another button, but rather to an arbitrary loc string:

Code: Select all

on mousemove
      if the mouse is down then set the rect of btn 2 to "200," & the mouseV & ",300,300" 
end mouseMove

There is no bogus color change. Something about the rect of another button??? Impossible.

Found out that if the cursor touches btn 2, the purple thing appears. if it does not, normal colors. In my test, the mouseV and the top of btn 2 are coincident. If I have the cursor ride just above the top of btn 2, back to normal colors in both directions.
