emWin GUIBuilder做的一个界面在F429I-DISCO上不显示是怎么回事？

用的是STM32Cube_FW_F4_V1.11.0ProjectsSTM32F429I-DiscoveryApplicationsSTemWinSTemWin_HelloWorld 这个例程，把builder生成的.c文件加入了工程，然后用生成的一个函数---CreateWindow();替换了MainTask（）函数里的代码。编译通过后，下载到板子里，黑屏。调了好长时间，就是什么都不显示。。下面是Builder生成的代码：

void MainTask(void) {
  GUI_Clear();
  GUI_SetFont( GUI_Font20_1);
  //GUI_DispStringAt("Hello world!", (LCD_GetXSize()-100)/2, (LCD_GetYSize()-20)/2);
  CreateWindows();
      while(1){
            GUI_Delay(10);
      }
}

复制以上代码即可运行,是因为你没有对界面进行刷新.
