TreePanel w/AsyncTreeNode Icon Issues

[Jul]

My AsyncTreeNodes are changing their icons dynamically by sending back different class names with the cls: attribute. It's been working great. My CSS code for each custom icon looks like this:
.treemenu-user-node .x-tree-node-icon {
background:transparent url(/icons/User.gif) repeat scroll 0%;
}

However, I continued to tweak my TreePanel design a bit further and found a problem. I wanted to also control the folder icons. FireBug revealed the css classes to use (or so I thought) and I wrote a pair of css classes to deal with closed and open states. Here's what those look like:
.treemenu-blue-folder .x-tree-node-collapsed .x-tree-node-icon {
background:transparent url(/icons/FolderClosed.gif) repeat scroll 0%;
}
.treemenu-blue-folder .x-tree-node-expanded .x-tree-node-icon {
background:transparent url(/icons/FolderOpen.gif) repeat scroll 0%;
}

Those are being ignored no matter what I seem to do. The default folder icons are used. Any suggestions on what's wrong?

Thanks,
Jul

Hi Jul,

This thread in the bug forum should help:

http://extjs.com/forum/showthread.php?t=3937

It links to another thread that has even more info.

In SVN, there is a new attribute "iconCls" which can be used to work around this issue.

Let me know if this solves the problem for you.

Thanks.

Hi Jack,

Thanks for the link. I see someone beat me to that problem.

Well, I have everything checked out from svn, but the file structure is in a different format from the normal file archives I'm used to. It looks like the *-all.js files, which I use, haven't been built.

I'm sure there must be a way to create those files. Once I figure this building process out, I'll check the iconCls update and let you know how it works.

Maybe I'm being dense, but I can't seem to find anything on how to build the ext-all.js file from the code in svn. The forum doesn't allow you to search for svn or "ext-all" and I've read several pages back in the forums without any success.

Any pointers on where to look would be greatly appreciated.

Thanks,
Jul

Included in SVN are jsb project files (3 of them). With those files and JS Builder (http://code.google.com/p/js-builder/) you can the exact same download distributed for Ext.

Thanks for the pointer on how to build the files. I have everything built now. I'll start testing the new iconCls functionality.

The "iconCls" attribute works perfectly.

I have one icon that needs to be the same whether it's expanded or contracted. I had to experiment, but I found that this css will work:

.x-tree-node-el .treemenu-user-folder {
background:transparent url(/icons/User.gif) repeat scroll 0%;
}

I hope using .x-tree-node-el in the selector is OK.

Thanks for your help!

No problem. Thanks for for letting me know it worked. :)
