Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: How do I remove scrollbars from the iframe within the mouseover popups?
I need to launch iFrame javascript functions from the parent.
A: Try to set exact width and height for the IFRAME.
Q: Is there a way we can add javascript behaviors to the popup menu in java actions? For example, is there a way we can add an onClick function to a popup menu in java item (eg, onClick="return MyFunction( )" ) so that we can catch and process key events?
I'm really hoping there's a way of doing this...
A: Unfortunately, you can't assign onmouseover/onClick/onContextMenu event to each item. However, you can achieve this by using standard html objects within popup menu in java items, for example:
var menuitems = [
["<div onContextMenu='your_code_here'>item text</div>", ""]
];
You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
Q: It's been couple of months since I last time asked something about tree menu. I am still evaluating the software.
I have a short question. Is it possible to use CSS instead of JavaScript to tune the look and feel of the tree menu? For example I would be interested in giving menu css java item height value in relative numbers (em or %) rather than specifying a size in pixels...
A: But actually you can use 'em' and '%' units in Deluxe Tree, forexample.
var tmenuWidth="13em";
var tmenuHeight="12em";
var tmenuWidth="35%";
var tmenuHeight="15em";
