Touchgfx(交互系统和创建无触发交互)

（一）目的是让Touchgfx给我们自动生成一些函数
（1）Screen1View.cpp

#include <gui/screen1_screen/Screen1View.hpp>
#include <touchgfx/Unicode.hpp>
Screen1View::Screen1View()
{
		num = 0;
}
void Screen1View::setupScreen()
{
    Screen1ViewBase::setupScreen();
}
void Screen1View::tearDownScreen()
{
    Screen1ViewBase::tearDownScreen();
}
void Screen1View::addButtonClickHandler()
{
		num++;
		Unicode::snprintf(textArea1Buffer,TEXTAREA1_SIZE,"%d",num);
		textArea1.invalidate();
		newTrigger();
		if(num==5)
			application().gotoScreen2ScreenSlideTransitionWest();
}
void Screen1View::newAction(int32_t val)
{
	touchgfx_printf("执行了newAction,参数值为:%d",val);
}

（2）Screen1View.hpp

#ifndef SCREEN1VIEW_HPP
#define SCREEN1VIEW_HPP
#include <gui_generated/screen1_screen/Screen1ViewBase.hpp>
