Unless I misunderstand the question, you can add a mouse listener or cursor listener to any JME Spatial with:http://jmonkeyengine-contributions.github.io/Lemur/javadoc/Lemur/com/simsilica/lemur/event/MouseEventControl.html http://jmonkeyengine-contributions.github.io/Lemur/javadoc/Lemur/com/simsilica/lemur/event/CursorEventControl.html
Cursor listeners are nice when you want to know where the spatial was clicked. Else MouseEventControl is probably what you want as it basically uses the regular JME mouse listeners.
You can see an example here:
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…
Use the PopupState to show your popup window. It has several options for blocking (or not) clicks… to include even graying out the background while the window is up.
The Lemur demos app has an example. (App code here: https://github.com/jMonkeyEngine-Contributions/Lemur/tree/master/examples/demos )
But this is the most relevant bit to your question:
Panel popup = createPopup(true);
randomizeLocation(popup);
getState(PopupState.class).showPopup(popup, closeCommand);
}
protected void createModalPopup() {
Panel popup = createPopup(true);
randomizeLocation(popup);
getState(PopupState.class).showModalPopup(popup, closeCommand);
}
protected void createColoredModalPopup() {
Panel popup = createPopup(true);
randomizeLocation(popup);
// Create a random color.
float r = (float)(Math.random() * 0.75 + 0.25);
float g = (float)(Math.random() * 0.75 + 0.25);
float b = (float)(Math.random() * 0.75 + 0.25);
