[Laszlo-user] edittext hiliting

[Henry Minsky]

There is an article I found which suggests a workaround using colortransforms

http://www.digitalflipbook.com/archives/flash/

Something like this may work. It is following the idea in the article,
to basically invert the color transform on the
movieclip containing the text field, and then set the text foreground
and background color to the inverse of what you want.

I just did this by experimenting with black and white, ideally you
would use something based on their
approach of actually inverting the colors using the color transform based on
the
foreground and bgcolor of the textfield that you desire.


<canvas>
  <simplelayout axis="y"/>
  <class name="myinputtext" extends="inputtext" >
     <handler name="oninit">
           var field = this.sprite.__LZtextclip;
           field.backgroundColor = 0xffffff;
           field.textColor = 0x000000;

           // invert the color transform for the sprite
           var colorTrans = {
           ra: -100,//  is the percentage for the red component (-100 to
100).
           rb:  0xd3,// is the offset for the red component (-255 to 255).
           ga: -100, // is the percentage for the green component
(-100 to 100).
           gb: 0xd3, // is the offset for the green component (-255 to 255).
           ba: -100,// is the percentage for the blue component (-100 to
100).
           bb: 0xd3,// is the offset for the blue component (-255 to 255).
           aa: 100,// is the percentage for alpha (-100 to 100).
           ab: 0 // is the offset for alpha (-255 to 255).
           };
          this.sprite.setColorTransform(colorTrans);
      </handler>
   </class>
  <myinputtext name="field" width="300" fgcolor="0xFFFFFF"
bgcolor="0x000000" height="30" fontsize="13">Is this selection
visible?</myinputtext>
  <myinputtext name="field2" width="300" fgcolor="0x999999"
bgcolor="0x333333" height="30" fontsize="13">Is this selection
visible?</myinputtext>
