toggle the text color in a field

[keram]

Hi,

Here is a very basic task that I want to accomplish:
Toggle the color of the text line in a field. Trying with the code below but it doesn't work.

Code: Select all

on mouseUp
   if the textColor of (clickLine())  = "blue"  then 
      set the textColor of  (clickLine()) to "red"
   else 
      set the textColor of  (clickLine())  to "blue"
   end if
end mouseUp

What's wrong with that code?

If you check the value of the textColor you'll see that although LC allows you to use a variety of constants to assign colors, the actually stored value for colors is RGB. In the case of blue that's 0,0,255, so this change makes it work:

Code: Select all

   if the textColor of (clickLine())  = "0,0,255"  then

Thanks Richard,

It works OK now. Still it's surprising that I only had to change the first line, the other two with the color names remained the same and the toggling works. Also if I put this line: set textColor of fld "d" to blue into a button it will change the text color in field d. So it seems that sometimes it works with just names of colors and sometimes not.

Watch out for empty lines -- If you click on an empty line you will get an error message.
That is because the clickline will not return a value.
I've added another line that will exit to top if you click on an empty line.

------------------------------------------------------------------
on mouseUp
if the value of the clickline is empty then exit to top

if the textColor of (clickLine()) = "0,0,255" then
set the textColor of (clickLine()) to "red"
else
set the textColor of (clickLine()) to "blue"
end if
end mouseUp
------------------------------------------------------------------
attached example.
Try commenting out the line I inserted and click below the bottom text on an empty line.

Thanks Paul,

It's good to know what you added.
I added 1 empty line between these 5 lines but not after the last one (yz). Then commented out your added line and still when clicking on the empty lines between the lines with the 'words' there is no error message. But clicking below the last one does create an error message (see the stack).

An additional comment to Richard's post:
If I create a field with a text in it and put this code into the field's script:

Code: Select all

on mouseUp
     if the textColor of me  = "blue"  then 
      set the textColor of  me to "red"
   else 
      set the textColor of  me  to "blue"
   end if
   end mouseUp

then the toggling works OK even though I did not use the numerical values for colors. There is some inconsistency there...
