SCroll text by pixels

Reemski · **Posted:** August 31st, 2006, 3:53 pm

Is there a way to scroll text by a certain amount of pixels or lines.
I know the textBox.scroll('pageDown') function, but this one is nog smooth.

I try to make a smooth scroll of exactly 2 lines each time.
Doing this with percentages is kinda confusing.
I'm trying to work it out, but somehow it doesn't really work the way i want it to...

Current script is (still in debugging stage ;-)

..):

Code:

function scrollRssDown(txtField) 
{
   alert( 'doScroll' )

   // check how much is visible -> this is 2 or something lines.
   var scrInfo    = eval(txtField + ".GetScrollInfo();");
   var framePerc   = scrInfo.vvisible
   var curPos       = scrInfo.vpos
   alert( scrInfo.vvisible )
   alert( scrInfo.vpos )

   var newPos       = 100 ;
   var stepSize    = 1
   if(scrInfo.vpos < 105) {
      while(curPos < newPos) {   // for a smooth scroll
         curPos += stepSize
         eval(txtField + ".SetScrollPosition(curPos);");
         wait(0.01);
      }
   }

   var scrInfo    = eval(txtField + ".GetScrollInfo();");
   alert( scrInfo.vpos)
}

Hi

Brenden Knifton on the DW support team, may still have a copy of an .imp file called scroll.imp that he developed, which has some helpful ways to construct scrolls, vary speed, etc. Why not write to him at DW support or send a pm on the Forum? Perhaps, he can post it or send along a copy.

Hope this helps.

Kind Regards,

I no longer have the example that Stephen mentioned. Attached is a very simple example of a smother scroll. What I have done is place a text object within a frame and then used the move object action to scroll the text pixel by pixel.

Hi Brenden

I've sent the scroll.imp file to you at DW support.

Kind Regards,

I posted this on the forum because this way other users can find this info later on.
When I receive an email with the info, no one else who later searches for it will find it.

Hi

Yes, it would be a good idea to post samples on the Forum for all to use.

Since I did not create the scroll.imp file, it would not be appropriate for me to post someone else's work. Brenden Knifton, at DW, is the file's author, which to me means that he is the only person who can or cannot place it on the Forum.

I've sent him a copy of the original file that he had sent to me by email, so that he can (1) decide whether he wants to post it, and (2) if he does want to post it, to go ahead and do so.

Kind Regards,

Brenden won't mind.
