Hello @PZamb.2 ,

You can easily do it with a toggle button for example, but you can also do it with a regular button based on the pressed state (with the getPressedState() function) of it.
Do you want support to make the fade animation or is it the button part that you need help on?

Hallo

Thank for your answer, i create fade botton on/off with option "Add C Code" and implemented a virtual function in screenView:

void screenView::function1()
{

if (ROI_Txt.getAlpha()>200) {
ROI_Txt.clearFadeAnimationEndedAction();
ROI_Txt.setFadeAnimationDelay(6);
ROI_Txt.startFadeAnimation(0, 120, touchgfx::EasingEquations::linearEaseIn);
}
else
{
ROI_Txt.clearFadeAnimationEndedAction();
ROI_Txt.setFadeAnimationDelay(6);
ROI_Txt.startFadeAnimation(255, 120, touchgfx::EasingEquations::linearEaseOut);
}
}

I'll Try your suggest.

Thank
