用ucGUI建立了一个窗口和一个按键，程序跳不出来了，是什么原因？

lzw520

用硬件仿真器观察，程序进入GUI_ExecDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), &_cbCallback, 0, 0, 0)后就再也没出来，
跟踪进入 GUI_ExecDialogBox发现程序在GUI_ExecCreatedDialog里没出来，再进入GUI_ExecCreatedDialog里发现程序在

  while (!DialogStatus.Done) {

    if (!GUI_Exec()) {

      GUI_X_WAIT_EVENT();      /* Wait for event (keyboard, mouse or whatever) */

    }

  }
程序在这里一直循环，不知道为什么，
这就导致程序不能进行其他的任务，比如触摸屏坐标获取任务。。。
不知道大家遇到过这样的问题没有，求解！

楼主上代码呀····还不会移植触摸屏呢~~~~~~~~~~~~~~~·····借来参考参考谢谢

我的触摸功能也没成功，网上都有视频教程移植了，好像是奋斗出的，怎么不去看看

楼主问题解决了吗，我用的emwin5.22，利用自带的CHOOSEFILE（...）函数创建的文件管理，调用GUI_ExecCreatedDialog（）后出不来了。不过我的看不到源码，是一个封装库文件，

回复【5楼】glyxz1990:
---------------------------------
GUI_ExecDialogBox是阻塞对话框，你用GUI_CreateDialogBox

glyxz1990

回复【6楼】lzw520:
---------------------------------
我知道GUI_ExecDialogBox是阻塞对话框，但是用到了CHOOSEFILE函数了，只能通过执行GUI_ExecDialogBox来处理啊，但是一用到GUI_ExecDialogBox就死了。
还有个问题就是，用到GUI_MessageBox（）函数也会死掉，原因可能是里面也用到了GUI_ExecDialogBox，所以只要一用到GUI_ExecDialogBox就死了。

回复【7楼】glyxz1990:
---------------------------------
GUI_ExecDialogBox函数里有这么一段：
while (!DialogStatus.Done) {
    if (!GUI_Exec()) {
      GUI_X_WAIT_EVENT();      /* Wait for event (keyboard, mouse or whatever) */
    }
  }    这个值DialogStatus.Done一直是0，所以程序会阻塞在这个while循环里，跳不出来。
你说的自带的CHOOSEFILE不是emWIN里的吧。
“用到GUI_MessageBox（）函数也会死掉”，这是指死机么？

---------------------------------
GUI_MessageBox()是不是死机还是出不来，我没有调试，不清楚。我单独测试GUI_MessageBox还想可以执行，不知道是不是多对话框处理不好的问题。
