LED as long as button pushed

How can I develop (with QML) an app which is capablet to flash the front LED in cyan as long as the button is pressed?

 

Thank you for your answer!

Re: LED as long as button pushed

There is no LED object exposed to Cascades QML, so you would either need to expose a LED class yourself or call a function in your C++.

 

Take a look here for how to do this...

Either way yes it would be in the onClick slot.

 


If you've been helped click on Like Button, if you've been saved buy the app. Smiley Happy

Re: LED as long as button pushed

Hi.

 

"as long as" means to me that you want to know when the button is being held down.

 

The clicked signal only shows you when it has been released. You may find one of the Gesture Handlers is suitable - you may need to connect to the touch signals.

 

Thanks,
