Getting mouseColor from outside the app window

[Kevin Stallibrass]

Hi,

 

I want to sample the color under the cursor and am using

 

set the cursor to cross

  repeat until the mouseClick

     set the backgroundColor of graphic "sample" to the mouseColor

     put the mouseColor into fld "rgb"

 

  end repeat

set the cursor to arrow

 

This works fine within the confines of the rev app window but is it possible
to sample a color from anywhere on the screen? 

Using the above script captures the color outside the rev app window and
puts the color into the graphic as the mouse moves but the mouseClick is
ignored when the cursor is outside the app window

Seems logical that it should act this way but there must be a way to get
round this. I'd be grateful for any pointers

 

Regards
