SceneView.onSceneGUIDelegate GUI sorting problem
I'm making some editor extensions and so far, I have a Non-MonoBehaviour (not editor) script (SceneViewEx) that adds some stuff to the scene view (using SceneView.onSceneGUIDelegate in the script's constructor) and a custom editor for a Mono-Behaviour script (ItemEditor) that also draws some stuff to the scene view (GUI.Button at the gameobject's position).
However, for the gameobjects, I'm not using OnSceneGUI because I want the buttons to always be visible, so instead I'm using OnDrawGizmos and again, use SceneView.onSceneGUIDelegate to draw the buttons (has to be OnSceneGUI for them to be interactable). The problem is that the buttons for the Item components are being drawn on top of the SceneViewEx's GUI elements. I've tried GUI.depth but it doesn't work at all. I suspect this is being caused by the Execution Order of the scripts, or to be more exact, the order of the delegate's listeners, however I can't set their Execution Order because they are not Mono-Behaviour scripts (I can set Item's order, but making it earliest or latest didn't change anything).
To sum up: SceneViewEx is a Non-MonoBehaviour script that uses SceneView.onSceneGUIDelegate to draw on Scene View GUI, ItemEditor is an editor script which also uses SceneView.onSceneGUIDelegate inside OnDrawGizmos to draw interactable buttons in the Scene View GUI even when object is not selected. ItemEditor's GUI is being drawn on top of SceneViewEx's GUI and I don't want that.
Is there anyway to make ItemEditor's GUI draw behind SceneViewEx's GUI, or make onSceneGUIDelegate execute ItemEditor's function first, then SceneViewEx's?
Alright, after asking how to reorder the delegate's execution order, I ended up following that method. In the ItemEditor script, after adding to the onSceneGUIDelegate, I remove the SceneViewEx's OnGUIFunc then add it again, this ensures that SceneViewEx's will be executed last and thus drawn on top of everything else. Although this tank my editor performance quite a lot, it works.
