I'm working on something that makes handling tree-view controls a little easier. However, I don't see how to add images to an item.

Matty and I made a tree-view class some time ago. The code isn't very beautiful and properly could use a rewrite, but it should be readable enough to understand how it works.
Basically, to add an item you send a TVM_INSERTITEM message with a TVINSERTSTRUCT. To change an item you send a TVM_SETITEM message with a TVITEM structure.

I've read your class hours ago, and I am afraid.. well.. ya know If I'd understood the image-handling thingy, I wouldn't have posted

Wow that is SO ugly... I can't believe we, at one point, wrote that...

Yeah.. Can't read it @Matti: think you need to check encoding etc. Or just pack it to a ZIP file

Save the file as a JS file and open it in Notepad++. It is a unicode file.

Well, I've got the file here as well, as Countdown Live uses it, and I use CDL

But that doesn't really solve my problem

Then what is the problem you're having? Do you need to add a new image to the tree's image list or something? Or do you have trouble finding what arguments to pass to those functions?

I've got absolutely no idea how to add an item with an image. So that's pretty much both.

Well, first of all you'll need to put some images in the tree view's image list. In order to prevent Plus! from messing up the image indexes, I always prefix the image ID with the image position.

xml code:

---

<Control xsi:type="TreeViewControl" Id="MyTree">
    <Position Left="10" Top="10" Width="100" Height="150" />
    <Images>
        <NormalIcons>
            <Image Id="01-folder">
                <Name>icon-folder</Name>
            </Image>
            <Image Id="02-file">
                <Name>icon-file</Name>
            </Image>
        </NormalIcons>
    </Images>
</Control>

Now to add an item, you can use TreeView::addItem.

js code:

---

var tree = new TreeView(PlusWnd, "MyTree");
var parentNode = tree.addItem("My folder", 0, 0);
var childNode = tree.addItem("My file", parentNode, 1);

---

This will add a root node with a child node to the tree. The root node will have a folder icon and the child node will have a file icon (assuming that you have those images in your script).
