Movieclip: Gettextdata And Addscroll, Automate common text field operations. Options

[gsb]

PURPOSE:
These two prototypes, getTextData and addScroll, are applied to a movieclip to load external text into the movieclip's associated text field and when loaded, to add a vertical scroll bar if needed.

SPECIAL NOTE: The addScroll requires a SWiSHmax build of 2004.04.30 or later.

PROTOTYPE:

CODE

// Load data from url into text field
movieclip.prototype.getTextData = function(url) {
    this.tfLoader=new LoadVars();
    this.tfLoader.self=this;
    this.tfLoader.onData=function(s) {
        delete this.self.onEnterFrame;
        if(typeOf(s)=="string") {
            if(!this.self._text.html) {
                s=s.split("\r").join("");
                this.self._text.text=s;
            } else this.self._text.htmltext=s;
            this.self.addScroll();
        }
        delete this.self.tfLoader;
    };
    this.tfLoader.load(url);
    this.onEnterFrame=function() {
        this._text.text=((x=this.tfLoader.getBytesTotal())>0Math.ceil(100*this.tfLoader.getBytesLoaded()/x):0) add "% loaded";
    };
};

// Add vertical scroll bar to text field and show if needed
movieclip.prototype.addScroll=function(sbw,sbfc,sbbc) {
    if(typeOf(this._text.onScroller)!="function") {
        var obj=this._text;
        if(typeOf(obj)!="object") return;

                    br.endFill();
                }
            }
        };
    } else this._text.onScroller();
};

USAGE: textfield.getTextData( "textfield.txt" );

EXAMPLE:

CODE

// SWiSH text field initialization
  textfield1.getTextData( "textfield1.txt" );

  // ActionScript text field initialization
  o=createEmptyMovieClip("textfield2",1);
  o.createTextField("_text",0,200,40,120,80);
  (o=o._text).border=1;
  o.multiline = true;
  o.wordWrap = true;
  o.html = true;
  textfield2.getTextData( "textfield2.txt" );

gsb any chance you could add a preview of this, sorry I'm extremely lost in what this actually is lol

blonde moment

[gsb]

Well, I guess so, although my intent was a "code junkies corner." LOL

Here is the above example as is: .: LINK :.

And this is another with a large text file to show the load progress: .: LINK :.

In other words, it loads the text data and draws the vertical scroll bar.

I would love to see the examples when you are back on line.

[kikezea]

This is a very powerfull script, but i´m sorry it doesn´t work with me, i´m shure it´s my fault, can you explain more the scritp, if you have to create the text in swish, in what places will be each script.


Thanks, Regards
