I am using the drop-down menu tutorial I found on tihs site and love it! However, I am trying to add a little tweak in here so that when the user rolls out of the submenu or the main menu, it disappears. May seem a bit out, but in the context of the bigger project, which I won’t explain here, this makes sense.
The problem is that I can’t have another rollout event for the entire menu as it conflicts with the submenu rollouts. If that makes any sense.
Here is the script I have now:
// generates a list of menu items (effectively one menu)
// given the inputted parameters. This makes the main menu
// as well as any of the submenus
GenerateMenu = function(container, name, x, y, depth, node_xml) {
// variable declarations
var curr_node;
var curr_item;
var curr_menu = container.createEmptyMovieClip(name, depth);
var menuBackground = container.createEmptyMovieClip(name, depth);
var menuHeight;
// for all items or XML nodes (items and menus)
// within this node_xml passed for this menu
for (var i=0; i<node_xml.childNodes.length; i++) {
numofitems=node_xml.childNodes.length;
// movieclip for each menu item
curr_item = curr_menu.attachMovie("menuitem","item"+i+"_mc", i+1);
curr_item._x = x;
curr_item._y = y + i*curr_item._height;
curr_item.trackAsMenu = true;
//measure height of main menu
menuHeight = curr_item._height*numofitems+16;
trace(menuHeight);
// item properties assigned from XML
curr_node = node_xml.childNodes*;
curr_item.action = curr_node.attributes.action;
curr_item.variables = curr_node.attributes.variables;
curr_item.name.text = curr_node.attributes.name;
curr_item.linkDescription.text = curr_node.attributes.linkDescription;
curr_item.linkIcon.loadMovie(curr_node.attributes.linkIcon);
// item submenu behavior for rollover event
if (node_xml.childNodes*.nodeName == "menu"){
// open a submenu
curr_item.node_xml = curr_node;
curr_item.onRollOver = curr_item.onDragOver = function(){
var x = this._x + this._width;
var y = this._y + 8;
GenerateMenu(curr_menu, "submenu_mc", x, y, 1000, this.node_xml);
// show a hover color
var col = new Color(this.background);
col.setRGB(0xf4faff);
};
}else{ // nodeName == "item"
curr_item.arrow._visible = false;
// close existing submenu
curr_item.onRollOver = curr_item.onDragOver = function(){
curr_menu.submenu_mc.removeMovieClip();
// show a hover color
var col = new Color(this.background);
col.setRGB(0xf4faff);
};
}
curr_item.onRollOut = curr_item.onDragOut = function(){
// restore color
var col = new Color(this.background);
col.setTransform({ra:100,rb:0,ga:100,gb:0,ba:100,bb:0});
};
// any item, menu opening or not can have actions
curr_item.onRelease = function(){
Actions[this.action](this.variables);
CloseSubmenus();
CloseMainMenu();
};
/*menuBackground.onRollOut = function(){
if(!mainmenu_mc.submenu_mc.hitTest(_root._xmouse, _root._ymouse, true)){
CloseMainMenu();
}
}*/
} // end for loop
currMenuBackground = menuBackground.attachMovie("background","background", 0);
currMenuBackground._x = x;
currMenuBackground._y = y - 8;
currMenuBackground._yscale = menuHeight;
};
// create the main menu, this will be constantly visible
CreateMainMenu = function(x, y, depth, menu_xml){
// generate a menu list
GenerateMenu(this, "mainmenu_mc", x, y, depth, menu_xml.firstChild);
// close only submenus if visible durring a mouseup
// this main menu (mainmenu_mc) will remain
mainmenu_mc.onMouseUp = function(){
if (mainmenu_mc.submenu_mc && !mainmenu_mc.hitTest(_root._xmouse, _root._ymouse, true)){
CloseSubmenus();
}
};
mainmenu_mc.onRollOut = function(){
if(!mainmenu_mc.submenu_mc.hitTest(_root._xmouse, _root._ymouse, true)){
CloseMainMenu();
}
}
};
// closes all submenus by removing the submenu_mc
// in the main menu (if it exists)
CloseSubmenus = function(){
mainmenu_mc.submenu_mc.removeMovieClip();
};
//closes the main menu by removing the movie clip
CloseMainMenu = function(){
mainmenu_mc.removeMovieClip();
trace("CloseMainMenu");
}
// load XML, when done, run CreateMainMenu to interpret it
menu_xml = new XML();
menu_xml.ignoreWhite = true;
menu_xml.onLoad = function(ok){
// create main menu after successful loading of XML
if (ok){
CreateMainMenu(10, 10, 0, this);
message_txt.text = "message area";
}else{
message_txt.text = "error: XML not successfully loaded";
}
};
// load first XML menu
menu_xml.load("menu1.xml");
