I have a simple TreePanel. I would like to select a particular node upon loading it. The nodes are from a remote file json. The tree is loading as expected. However, the node is not being selected. Firebug shows node as undefined.
This perhaps because of the async property. But, I an unable to configure this other wise, or specify the node be selected. I haven't tried this in a TreePanel but since the TreeGrid is based on it I'll just assume this works.
I used the load event of the loader to plugin similar code after the XHR request was done, so try to write your setNode function like this:. You can accomplish that by traversing the tree and node. This is because the node isn't really selectable until the tree has been rendered. Try adding your node selection to an event listener listening for the render event. If you're using a recent enough version of ExtJS then I find using ViewModels and the Selection config far easier for this kind of thing.

Custom Template for Ext. TreePanel Overview Despite the numerous plug-ins out there I haven't been able to figure out how to apply a custom template to the nodes in my Ext. It is a custom form that parses large XML request and builds up the array nodes. I need to customize the formatting of the output to include various extra fields and information.
In the basic case I would like to be able to do this: Code:. I tried adding the same option to the other treenodes without success. Here is what I added to get it to work for the root node only Code:. Custom UI Hows the current code works for your? Have you finalize your code? I need this code for my application I'd love to see completed code I'm having trouble getting nodes to custom render. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.
To patch the bug in Ext. The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good". List of strings to be concatenated into template. Alternatively an array of strings can be given, but then no config object may be passed.
This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further in any way, including access to its methods and properties. To prevent potential memory leaks, all object references will be nulled at the end of destruction sequence, unless clearPropertiesOnDestroy is set to false. Returns a specified config property value. If the name parameter is not passed, all current configuration options will be returned as key value pairs.
Calling btn. Applies the supplied values to the template and inserts the new node s as the first child of el. Adds a "destroyable" object to an internal list of objects that will be destroyed when this instance is destroyed via destroy.
Applies the supplied values to the template and overwrites the content of el with the new node s. Get the reference to the class from which this object was instantiated.
Note that unlike Ext. Base self , this. Destroys a given set of linked objects. This is only needed if the linked object is being destroyed before this instance. Adds new config properties to this class. This is called for classes when they are declared, then for any mixins that class may define and finally for any overrides defined that target the class. Class optional. Pass true if the members are private. This only has meaning in debug mode and only for methods.
The new method name, or an object to set multiple aliases. See flexSetter. Creates a template from the passed element's value display:none textarea, preferred or innerHTML. Gets an XTemplate from an object an instance of an Ext define 'd class. Many times, templates are configured high in the class hierarchy and are to be shared by all classes that derive from that base.
To further complicate matters, these templates are seldom actual instances but are rather configurations. For example:. The goal being to share that template definition with all instances and even instances of derived classes, until someTpl is overridden. This method will "upgrade" these configurations to be real XTemplate instances in place to avoid creating one instance per object. The resulting XTemplate will have an owner reference injected which refers back to the owning object whether that is an object which has an own instance , or a class prototype.
Through this link, XTemplate member functions will be able to access prototype properties of its owning class. The object from which to get the XTemplate must be an instance of an Ext define 'd class.
Override members of this class. Overridden methods can be invoked via Ext. Base callParent. Direct use of this method should be rare. Use Ext. The above accomplishes the same result but can be managed by the Ext.
Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class My. The properties to add to this class. This should be specified as an object literal containing one or more properties. Ext JS Terms of Use. Docs Help. Container view source. Component protected.
