hello, you need to make your buttons movieclips, then use loadVars to load text files.

the links, are they normal getURL's or different things?

hi, okay your approach is totally different to what i had in mind. i was thinking along the lines of txt files.

at what point do you get NaN?

i've just copied your code, will give it a bang (xml and i arent' good friends).

hi, i think your problem is the xml hasn't had a chance to load yet.

i had a look through what documentation i had and here's what i'd do.

firstly, create a movieclip with 3 frames to simulate the up, over and down states of the buttons (if you want that). Then give it an identifier (in this example, its attached dynamically using attachMovie).

then, in the first keyframe.
menuXml = new XML();
menuXml.ignoreWhite = true;
menuXml.onLoad = function(success) {
      if (success) {
            menuItem = this.firstChild.childNodes;
            for (var i = 0; i<menuItem.length; i++) {
                  item = _root.attachMovie("itemClip", "itemClip"+i, i);
                  item._x = 0;
                  item._y = 20*i;
                  item.itemLabel.text = menuItem[i].attributes.name;
                  item.myUrl = menuItem[i].attributes.url;
                  item.onRollOver = function() {
                        this.gotoAndStop(2); //over state
                  };
                  item.onRollOut = function() {
                        this.gotoAndStop(1);//up state
                  };
                  item.onRelease = function() {
                        this.gotoAndStop(1);
                        getURL(this.myURL, "_blank");
                  };
                  item.onPress = function() {
                        this.gotoAndStop(3);
                  };
            }
      }
};
menuXml.load("myMenu.xml");

hope that makes sense.
in this example, the buttons are laid out to form a vertical menu, you can adjust the item._x and item._y according to your needs.

ok - go have a look here.
http://www.geocities.com/bluegenie_sa/pdd/menu.zip

check and take note of how i've set up my xml file, if yours is structured differently, then you'll need to change your structure in terms of the childnodes and attribute names.

to center the text simply center align your textfield.
you can change the autosize property of your textfield.
re. the rollover states, you'll notice that my example has them (remember your buttons have to be movieclips in order to acheive that).

In the end i will use this. it's better for what i want to make in the end

the problem i have is that i can not make the CSS file to work. after i define the style for links in the css file they do not have any impact.
any special setting i have to do ?



var css_styles = new TextField.StyleSheet();
css_styles.load("styles.css");
css_styles.onLoad = function(ok) {
      if (ok) {
            // display style names
            trace(this.getStyleNames());
      } else {
            trace("Error loading CSS file.");
      }
};
menuXml = new XML();
menuXml.ignoreWhite = true;
menuXml.onLoad = function(success) {
      if (success) {
            menuItem = this.firstChild.firstChild.childNodes;
            //for (j=1; j<=4; j++) {
            for (i=0; i<menuItem.length; i++) {
                  rand1.htmlText += "<a href=\""+menuItem[i].attributes.url+"\">"+menuItem[i].attributes.text+"</a>";
            }
            //}
      }
};
menuXml.load("meniu.xml");
