STM32F746G-DISCO, Button

I suppose you could do something like this: in Designer you create 2 interactions. The first one calls a new function when the button "ButtonNext" is clicked. The other interaction changes the screen when an hardware button is clicked. This is a fake button we use in order to generate the go to screen 2 transition function and use it in our code.

Then I added this in Screen1View.cpp

void Screen1View::functionNextOrStay()
{
 if (ButtonOnOff.getState() == TRUE) // getState returns TRUE when On 
 {
 application().gotoScreen2ScreenNoTransition();
 }
}

Tell me if this enough for what you need, I did not need to use setTouchable() since it does not influence the result.

Well a flex button doesn't have a on/off state but you can still trigger off that button. So for that flex button, the C++ code will check the current touchable state of the buttonNext and toggle the touchable state to the opposite.

if(buttonNext.isTouchable() == true)
{
 buttonNext.setTouchable(false);
 buttonNext.setLabelColor(touchgfx::Color::getColorFrom24BitRGB(255,0,0));
 buttonNext.setLabelColorPressed(touchgfx::Color::getColorFrom24BitRGB(255,0,0));
 buttonNext.invalidate();
}
else
{
 buttonNext.setTouchable(true);
 buttonNext.setLabelColor(touchgfx::Color::getColorFrom24BitRGB(255,255,255));
 buttonNext.setLabelColorPressed(touchgfx::Color::getColorFrom24BitRGB(255,255,255));
 buttonNext.invalidate();
}
