Lemur and Size of 3d spatial for layouts

[pspeed]

@Michael_Gattinger

this code is not possible, because addChild does not support to take a node as a parameter.

Container has an addChild() that takes a node… as does GuiControl. The point is that if you attach a child directly to the Panel then Lemur can’t know about it. You must pass it to one of the methods that cares about a layout. (Those methods will not work like you want without the child have its own GuiControl anyway.)

How to add a jme3-spatial to lemur gui and / or just make them clickable?

To just make a JME spatial clickable just add a Lemur mouse listener to it. There was even a lemur gem for this.

Lemur Gems #3 : Scene picking

Lemur has a robust picking subsystem that uses JME’s standard ray collision code. In this Lemur Gem, I add simple mouse picking to the app already built in Lemur Gem #1 and Lemur Gem #2 When you initialize Lemur’s GuiGlobals, it automatically adds the MouseAppState that does scene picking. It also adds the guiNode and rootNode to the pickable scene roots automatically. This demo uses that automatic setup. It is also possible to use the MouseAppState without the rest of Lemur but for simplic…

And it works in 2D or 3D.
