M5 tough remove touch buttons

[HansDia95]

Hello

I have tried everything when it comes to removing/hiding/deactivating a button on the touch screen on an M5 tough, searching Google in and out. When I use .fillScreen(), it fills the screen but I can still "click" the button when I touch the screen where it was and then it appears again.
Hoping for an answer to this small question.

Thanks a lot! :D

Hello @HansDia95

using UIFlow firmware 1.9.8 on my M5Tough I can simply hide a button and after that it no longer is touchable until I make it show again.

Have you tried Set touch_button_X hide block?

Care to share your UIFlow code?

Thanks
Felix

Hi again I'm using Arduino IDE btw :)

Thanks again :)

Hello @HansDia95

I assumed you are using UIFlow since you've posted under SOFTWARE / UIFlow ...

Anyways, with Arduino there seems to be an issue with hiding (static) buttons. However when I use dynamic buttons it seems to work. Here is a function creating / showing or hiding / deleting a button.

Button *b3 = nullptr;

void showHideButton3(bool show)
{
  if(show == true)
  {
    if(b3 != nullptr) return;

    Serial.println("*** show");
    b3 = new Button(220, 200, 80, 40, false, "C", off_clrs, on_clrs, MC_DATUM);
    b3->addHandler(eventDisplay, E_ALL);
  }
  else
  {
    if(b3 == nullptr) return;

    Serial.println("*** hide");
    b3->delHandlers();
    b3->hide(BLACK);
    delete(b3);
    b3 = nullptr;
  }
}

BTW: I was using above in the context of the M5Tough Touch example.
Thanks
Felix

Look in

https://github.com/m5stack/M5Tough/blob/master/src/utility/M5Button.h

It explains the touch button usage.

@skynorth Thanks A lot!!

it was button.hide(), but I had to fill the screen after.

Thanks!!! :)

@hansdia95 I am running into problems with using button.hide() Can you please provide an example of your usecase? Perhaps I just have a syntax error. I can not find much informaiton on this other than the writeup on github (that provides little informaiotn on this)
