Consuming keyboard events in custom editors

Archived Forums Questions & Answers

I am writing a custom editor. When this editor is in a specific state, I want it to get hold of keyboard input. There is GUIUtility.hotControl for mouse events, but what about keyboard events?

Example:

public void OnSceneGUI () {
    if (isMySpecialContextActive) {
        Event e = Event.current;
        if (e.isKey && e.keyCode == KeyCode.F) {
            DoSomethingWonderfulButPleaseDontFitSelectionToView();
        }
    }
}

I have tried e.Use() obviously, but that appears to be entirely non-functional here. I also tried GUIUtility.keyboardControl in the same way one would use hotControl. I really need to suppress default behavior entirely, even for bare keystrokes without Ctrl and Shift held down.

This is rather old by stumbled across this when googling and found the answer here Get KeyCode events in editor without object selected - Questions & Answers - Unity Discussions

So in case this is still useful to Zyl or other users, you would have to do:

public void OnSceneGUI () {
     if (isMySpecialContextActive) {
        int controlID = GUIUtility.GetControlID(FocusType.Passive);
        Event e = Event.current;
        if (Event.current.GetTypeForControl(controlID) == EventType.keyDown) {
            if(Event.current.keyCode == KeyCode.F) {
                DoWhatYouWantItWontFitSelectionToView();
            }
        }
     }
}

Disclaimer: At least it worked in my case, trying the exact same thing. To my shame, I do not understand WHY it works due to not understanding the Control-ID-thingy… but I’ll work on that. :wink:
