Dynamic TreeIcon in TreeGrid using SVG

[cyuen]

I am trying to customize TreeNode.icon dynamically in the TreeGrid for the nodeIcon (without a static image URL but dynamic update an image e.g. using SVG instead). However, the TreeNode.icon API seems to be restricted to be using a SCImgURL type only.

I just wonder if there is an alternate way to achieve that. Thanks.

An SCImgURL can be a "data:" URL, which can in turn embed SVG content (in browsers that support this).

Using the SVG as base64 works but not if it is unencoded...

where I would need the unencoded case.

Base64 encoding is easy to do on the fly.

The other option is to have the URL just point at an SVG file (again in supported browsers).
