XML Syntax:
|
||
|
|
<?xml version='1.0' encoding='iso-8859-1'?>
|
||
|
|
<tree id="0">
|
||
|
|
<item text="My Computer" id="1" child="1" im0="my_cmp.gif" im1="my_cmp.gif" im2="my_cmp.gif" call="true" select="yes">
|
||
|
|
<userdata name="system">true</userdata>
|
||
|
|
<item text="Floppy (A:)" id="11" child="0" im0="flop.gif" im1="flop.gif" im2="flop.gif"/>
|
||
|
|
<item text="Local Disk (C:)" id="12" child="0" im0="drv.gif" im1="drv.gif" im2="drv.gif"/>

|
||

|
</tree>
|
||
|
|
</XMP>
|
||
|
|
<strong><tree></strong> node is mandatory. It specifies the parent of loading block of data. According to this its id parameter specifies the ID oth that parent.
|
||
|
|
To load root level you need to specify the ID you used when created tree object: new myObjTree(boxObject,width,height,<b>0</b>) <br>
|
||
|
|
|
||
|
|
<strong><item></strong> can contain subitems (in order to load more than one level at once) or not.<br>
|
||
|
|
Mandatory parameters for this tag are:<br>
|
||
|
|
<li>text - label of the node</li>
|
||
|
|
<li>id - id of the node</li>
|
||
|
|
Optional parameters for this tag are:<br>
|
||
|
|
<li>im0 - image for node without children (tree will get images from the path specified in setImagePath(url) method)</li>
|
||
|
|
<li>im1 - image for opened node with children</li>
|
||
|
|
<li>im2 - image for closed node with children</li>
|
||
|
|
<!--- <li>top - </li> --->
|
||
|
|
<li>select - select node on load (0/1)</li>
|
||
|
|
<li>call - call function on select(0/1)</li>
|
||
|
|
<li>checked - check checkbox if exists(0/1)</li>
|
||
|
|
<li>child - spec. if node has children (1) or not (0)</li><br>
|
||
|
|
To set userdata directly within XML use <strong><userdata></strong><br>
|
||
|
|
It has just one parameter: <br>
|
||
|
|
<li>name</li><br>
|
||
|
|
and value to specify userdata value

|
|
<h4 onclick="openFull(this)">Setting custom icons to nodes</h4
|
||
|
|
><div style="display:none" class="block">
|
||
|
|
There are two ways to set custom icons for the node. And it depends on the way you add items.<br>
|
||
|
|
<em>Important:</em> tree will get images for the nodes from the path specified in setImagePath(url) method.<br><br>
|
||
|
|
|
||
|
|
Javascript way. Using arguments of insertNewChild(...) or insertNewNext(...) methods:
|
||
|
|
<XMP>
|
||
|
|
<script>
|
||
|
|
var im0 = "doc.gif";//icon to show if node contains no children
|
||
|
|
var im1 = "opened.gif";//if node contains children and opened
|
||
|
|
var im2 = "closed.gif";//if node contains children and closed
|
||
|
|
tree.insertNewItem(0,1,"New Node 1",0,im0,im1,im2);
|
||
|
|
tree.insertNewNext(1,2,"New Node 2",0,"txt.gif","opened.gif","closed.gif");
|
||
|
|
</script>
|
||
|
|
</XMP>
|
||
|
|
XML way. Using parameters of <item> tag:
|
||
|
|
<XMP>
|
||
|
|
<?xml version='1.0' encoding='iso-8859-1'?>
|
||
|
|

||
|
|
<item text="My Computer" id="1" child="1" im0="doc.gif" im1="my_opened.gif" im2="my_closed.gif">
|
||
|
|
</tree>
|
||
|
|
</XMP>
|
||
|
|
<li>im0 - image for node without children (tree will get images from the path specified in setImagePath(url) method)</li>
|
||
|
|
<li>im1 - image for opened node with children</li>
|
||
|
|
<li>im2 - image for closed node with children</li>

|

|
If your tree should contain large amount of nodes (or you simply do not want to waist time loading hidden nodes), it would be better to load them on demand, not at once.
|
||
|
|
For this purpose we made the tree to load levels dynamically using XML. <br>

tree=new dhtmlXTreeObject('treeboxbox_tree',"100%","100%",0);

...
|

|
|
var sID = tree.getSelectedItemId();//get id of selected node
|
||
|
|
tree.setLabel(sID,"New Label");//change label of selecte node
|
||
|
|
tree.setItemColor(sID,'blue','red');//set colors for selected node's label (for not selected state and for selected state)
|
||
|
|
tree.openItem(sID);//expand selected node
|
||
|
|
tree.closeItem(sID);//close selected node
|
||
|
|
tree.changeItemId(sID,100);//change id of selected node to 100
|
||
|

alert("This node has children: "+tree.hasChildren(100));//show alert with information if this node has children
