xml nav help

[gemma_olds]

Hi,

I have a small problem with xml navigation.

The nav is built and working fine the problem is I dont know how to make each button show a selected / active state.

I can make the button turn yellow and become disabled, stopping the rollout function.
this works but when I press another button it doesn't set the one pressed before it to return to its original state.

Because the menu it populated via xml and the movieclips are attached I am not sure how to reference them individually.

If any one could help that would be brilliant.

thanks


this the code =

menu_xml = new XML();
menu_xml.ignoreWhite = true;
menu_xml.onLoad = function(ok) {
if (ok) {
CreateMainMenu(245,132,1,this);
message_txt.text = "message area";
} else {
message_txt.text = "error: XML not successfully loaded";
}
};
menu_xml.load("nav.xml");


GenerateMenu = function (container, name, x, y, depth, node_xml) {;
var info_item;
var curr_node;
var curr_item;
var totalNav = curr_item.length;
var curr_menu = container.createEmptyMovieClip(name, depth);
for (var i = 0; i<node_xml.childNodes.length; i++) {;

// projects buttons;
curr_item = curr_menu.attachMovie("menuitem", "item"+i+"_mc", i);
curr_item._x = x;
curr_item._y = y+i*curr_item._height;
curr_item.trackAsMenu = true;
///load project nodes;
curr_node = node_xml.childNodes[i];
curr_item.action = curr_node.attributes.action;
curr_item.variables = curr_node.attributes.variables;
curr_item.name.text = curr_node.attributes.name;

//set project button states;
curr_item.onRelease = function() {
trace("click");
Actions[this.action](this.variables);
};

CreateMainMenu = function (x, y, depth, menu_xml) {
GenerateMenu(this,"mainmenu_mc",x,y,depth,menu_xml .firstChild);
};

// loads swf into holder
Actions = Object();
Actions.gotoURL = function(urlVar) {
vid_holder.loadMovie(urlVar);
};

it looks like your onRelease handler performs whatever action it found in the XML but I don't see where you're tracking the currently highlighted item. Usually I use a variable to store the instance name of the currentItem and then upon click, revert the state of currentItem to default before performing the desired button action & updating the currentItem variable to contain a pointer to the most recently clicked button.

you have a variable named curr_item but that's just used to generate the menu and it doesn't exist once GenerateMenu finishes running since your var declaration is inside the function.

Thanks for you reply,

I think i understand what you mean, do you think you could help me add the extra variable that i need so I can call the buttons individually.

Any help with the code would be great.

thanks
