How to close/stop widget by onKey-/onStop-event?

Hi,

I would like to stop / close a widget by the ESC-Key (2-Button Venu SQ). I would use an onKey-Event and determine, which button is pressed.

Which command to use to return from there to the onStop-function and to close the widget (at the moment I just close the device simulator manually.

Thanks

In general widgets can't do popView, Sys.exit() to close, but if you do a return false for KEY_ESC, the widget will close with a simple press of the lower button.

does this also trigger onStop() (because I need to do some value savings operations there before exiting)?

How do I construct this return false for the key?

function onKey()

....

get the value of the key

if key is ESC-Button then

return false;

onStop will be called when the widget exits. You shouldn't even need onKey() for that to happen. The default action of the back key is to exit the widget.

Understand that the back button is only one of the ways a widget exits. On devices without glances, up/down will also exit, and if you do nothing the widget times out and returns to the watch face. The timeout is in the 1-2 minute range.
