Nifty - creating drawable canvas as part of the GUI

[hermetic]

I’m having sort-of-same problem here:

Paint into an image in nifty, updated image does not change[solved]

Hi, I’m wondering how I get a own drawn image, or an edited image into nifty on-the fly changed outside simpleInitApp(). My problem is, that this works only in simpleInitApp() (imageMap is my edited image): NiftyImage nimg = new NiftyImage(nifty.getRenderEngine(), new RenderImageJme(new Texture2D(imageMap))); Element niftyElement = nifty.getCurrentScreen().findElementByName("monmapimage"); // swap old with new image niftyElement.getRenderer(ImageRenderer.class).setImage(nimg);…

Theoretical you can create a texture2D and exchange this new image for an old in nifty (see code in my question).
Sadly my solution only works in simpleInitApp() so far.

Let’s keep fingers pressed, some nifty-folks have a more generally working answer.
