al of the not works at all.

but the button picture changes

but it does not run any code in interaction...

Ok i download your code and get reply ... you create box1 and set change colour ... generator generate this in base

Screen1ViewBase::Screen1ViewBase() :
    buttonCallback(this, &Screen1ViewBase::buttonCallbackHandler)
{
 
    __background.setPosition(0, 0, 800, 480);
    __background.setColor(touchgfx::Color::getColorFromRGB(0, 0, 0));
 
    box1.setPosition(0, 0, 800, 480);
    box1.setColor(touchgfx::Color::getColorFromRGB(255, 255, 255));
 
    button1_1.setXY(292, 204);
    button1_1.setBitmaps(touchgfx::Bitmap(BITMAP_BLUE_BUTTONS_ROUND_EDGE_SMALL_ID), touchgfx::Bitmap(BITMAP_BLUE_BUTTONS_ROUND_EDGE_SMALL_PRESSED_ID));
    button1_1.setAction(buttonCallback);
 
    add(__background);
    add(box1);
    add(button1_1);
}
 
void Screen1ViewBase::setupScreen()
{
 
}
 
void Screen1ViewBase::buttonCallbackHandler(const touchgfx::AbstractButton& src)
{
    if (&src == &button1_1)
    {
        //Interaction1
        //When button1_1 clicked change color of box1
        //Set RGB color R:0, G:0, B:0 on box1
        box1.setColor(touchgfx::Color::getColorFromRGB(0,0,0));
        box1.invalidate();
    }
}

All is ok , but for this work need setup canvas buffer size or try little box2 10x10 pixel and will see. Plus place breakpoint in callback if it work
