[求助] UCGUI失去焦点，点击按钮没反应

chenfengjie90 2014-5-10 09:43 楼主

点击QUIT后执行的代码，这里我给背景窗口发了个消息，要它更新窗口，然后删除当前任务
case WM_NOTIFY_PARENT:
Id = WM_GetId(pMsg->hWinSrc);    /* Id of widget */
NCode = pMsg->Data.v;                /* Notification code */
switch (NCode)
{
case WM_NOTIFICATION_CLICKED:
   switch (Id)
   {
   case GUI_ID_BUTTON0:
      _ToggleFullScreenMode(hDlg);
      break;
   case GUI_ID_BUTTON1:
      {
      WM_MESSAGE Message;
   GUI_EndDialog(hDlg,1);
   GUI_Clear();
   Message.MsgId=wm_mypaint;
   Message.Data.p="hehe";
   WM_SendMessage(WM_HBKWIN,&Message); //给窗体发送消息，要重绘自己了。
      OSTaskDel(OS_PRIO_SELF);
      break;
      }
   }
   break;
背景窗体接受到这个消息执行下面一段代码
void _cbBkWindow(WM_MESSAGE *pMsg)
{
  int i, NCode, Id, Value;
  WM_HWIN hDlg;
  hDlg = pMsg->hWin;
  switch(pMsg->MsgId)
  {
  case  wm_mypaint:
      In_Menue();
      GUI_Delay(100);
      break;
  case WM_NOTIFY_PARENT:
Id = WM_GetId(pMsg->hWinSrc);    /* Id of widget */
NCode = pMsg->Data.v;                /* Notification code */
switch (NCode)
{
case WM_NOTIFICATION_CLICKED:
   switch (Id)
   {
   case GUI_ID_BUTTON0:
      out_MainMeue();//释放资源
      OSTaskCreate((void (*) (void *))MainTask,
                  (void *) 0,
                  (OS_STK *) &APP_MainTaskStk[TemP_Task_STK_SIZE - 1],
                  (INT8U) Main_Menue_Task_PRIO);
      break;
   case GUI_ID_CLOSE:
      GUI_DispStringAt("hehe",0,0);
      break;
   case GUI_ID_OK:
      GUI_EndDialog(hDlg,0);
      break;
   }
}    break;
  default:
WM_DefaultProc(pMsg);
  }
}

离开桌面时候，下面是释放桌面控件资源的
void out_MainMeue() //释放主窗体的资源
{
  int i;
  for(i=0;i<5;i++)
WM_DeleteWindow(Hbtn[i]);
}

下面是桌面控件初始化
void In_Menue()
{
  int i;

  Hbtn[0] = BUTTON_Create(20,20,80,80, GUI_ID_BUTTON0, WM_CF_SHOW);
  Hbtn[1] = BUTTON_Create(120,20,80,80, GUI_ID_BUTTON1, WM_CF_SHOW);
  Hbtn[2] = BUTTON_Create(220,20,80,80, GUI_ID_BUTTON2, WM_CF_SHOW);
  Hbtn[3] = BUTTON_Create(20,140,80,80, GUI_ID_BUTTON3, WM_CF_SHOW);
  Hbtn[4] = BUTTON_Create(120,140,80,80, GUI_ID_BUTTON4, WM_CF_SHOW);
  for (i = 0;i < 5;i++)
  {
// BUTTON_SetTextAlign(Hbtn[i],GUI_TA_BOTTOM | GUI_TA_LEFT);
BUTTON_SetFont(Hbtn[i],&GUI_FontHZ_MicrosoftFont_13);
BUTTON_SetTextColor(Hbtn[i],0,GUI_BLACK);
BUTTON_SetBkColor  (Hbtn[i],0,GUI_RED);
BUTTON_SetBkColor  (Hbtn[i],1,GUI_GRAY);
  }
  /* Set the button text */

  WM_SetDesktopColor(GUI_BLUE);
  BUTTON_SetText(Hbtn[0]," 温度监控");
  BUTTON_SetText(Hbtn[1]," 湿度监控");
  BUTTON_SetText(Hbtn[2]," 光照监控");
  BUTTON_SetText(Hbtn[3]," 参数设置");
  BUTTON_SetText(Hbtn[4]," 系统设置");
}

主界面就5个button，现在问题是，我点击QUIT后，成功跳转的主窗体，而且也删除了当前任务，但是桌面上那5个button按钮点击没有反应，。不知为何，希望大神们，帮小弟一把。毕业设计焦虑中啊。。、、
