Hiliting Buttons

[Rob Cozens]

Hi All,

Today's mystery is one I've been watching for some time, assuming 
sooner or later an answer would come to me.  It hasn't; so I'm asking 
for help:

What hidden property of a button can cause it not to display its 
hilite color &/or reverse its border colors when the handler it calls 
instructs "set the hilite of the target to true"?

I have a series of buttons that all appear (via the properties 
palette) to be set up identically; yet some buttons don't display 
their hilite color, and a few don't even reverse the border colors.

Button specifics for all buttons --

* Style = rectangle
* Opaque = true
* Ions : "regular", armed, & disabled
* Can receive focus = true
* Arm on mouseEnter = true
* Background & hilite colors are set
* 3D = true
* Show border = true
* Show focus border = true

Button script format:

on mouseEnter
   buttonEnter [helpFieldName]
end mouseEnter

Handler that "fails":

on buttonEnter helpField
   global inFocus
   if inFocus then exit buttonEnter
   lock screen
   set the hilite of the target to true -- COLORS DON'T CHANGE & 
BORDERS DON'T REVERSE ON SOME BUTTONS
   showHelpField helpField
   unlock screen
end buttonEnter

local lastHelpId

on hideHelpField
   if lastHelpId is not empty then
     hide field id lastHelpId
     put empty into lastHelpId
   else put empty into field "Help"
end hideHelpField

on showHelpField theField
   hideHelpField
   show field theField
   put the id of field theField into lastHelpId
end showHelpField

A great future add-on to Revolution would be functionality to have 
the Dev UI compare ALL properties of two controls of a similar type 
and return a list of properties that are set differently.

In the meantime, I hope someone can make it unnecessary for me to 
have to compare all properties manually.     :{`)

PS: The buttons were created by RunRev when it converted my HyperTalk 
version of OenoLog to a Revolution stack, in case that makes a 
difference.
