GUI - Is there an event called when the user presses Enter?

[Sme]

onBeforeKeyAddObservable doesn't pick up Enter presses, and onBlurAddObservable doesn't differentiate between the user pressing Enter and clicking outside of the TextInput. 

What I'm trying to do is have a chat box, so that the user can send the message simply by pressing Enter; but I can't find a way to determine when the user actually presses Enter.

Thanks

Answering my own question...

The solution I came up with was remove the event listeners from the InputText, and add a 'keydown' event listener to the canvas. Then in the canvas' keydown event, if the user presses enter, I process the chat input's current text and then clear it. Otherwise, I call the InputText.processKeyboard(e) method, with e being the KeyboardEvent passed via the onkeydown event, and let the InputText control process it from there.

 

private _chatInput : GUI.InputText;

...

document.getElementById('canvas').addEventListener('keydown', this._handleKeyDown.bind(this));

...

private _handleKeyDown(e : KeyboardEvent) : void {
    if (this._chatInput) {
        if (e.key === 'Enter') {
            this._chatInput.text = '';
        } else {
            this._chatInput.processKeyboard(e);
        }
    }
}

You could try this to not break the underlying handlers:

Basically detecting the next enter after onBlur to be sure.
