Hi all,
I've created a page very similar to the tutorial example at this link:
http://xulplanet.com/tutorials/xultu/treeviewdet.html
I'm having a problem with the twistys, namely that clicking on them has no effect. I get the desired result by calling my toggleOpenState function directly, but nothing happens when the twisty is clicked. What do I need to do to have the toggleOpenState function called when a twisty is clicked?
Sorry if this question has been handled previously, I searched the forum but couldn't find a working solution. Thanks for any help. |

I figured it out.
For anybody else who had the same issue, add the following to the treeView definition:
| Code: |
QueryInterface : function(aIID)
{
if (Components.interfaces.nsIClassInfo.equals(aIID) ||
Components.interfaces.nsITreeView.equals(aIID) ||
Components.interfaces.nsISupportsWeakReference.equals(aIID) ||
Components.interfaces.nsISupports.equals(aIID))
{
return this;
}
throw 0x80004002; // Components.results.NS_NOINTERFACE;
},
get flags() { return Components.interfaces.nsIClassInfo.DOM_OBJECT; },
|
The twistys should now function correctly
