当按键输入时能够进入 ExecSetup()，可是屏幕没有刷新，使用模拟器能够刷新出新界面，请问问题在哪？谢谢
static void _cbDialog1(WM_MESSAGE * pMsg) {
WM_HWIN hItem;
WM_HWIN hWinSrc;
char buf[50];
WM_HWIN hWin = pMsg->hWin;
int Id, NCode;
// USER START (Optionally insert additional variables)
GUI_UC_SetEncodeUTF8();
TEXT_SetFont(WM_GetDialogItem(hWin,ID_TEXT_0),&GUI_Fontsongfont36);
// USER END
switch (pMsg->MsgId) {
case WM_INIT_DIALOG:
//
// Initialization of 'Text'
//
hItem = WM_GetDialogItem(pMsg->hWin, ID_TEXT_0);
TEXT_SetText(hItem, "电压：");
TEXT_SetFont(hItem, GUI_FONT_16_HK);
TEXT_SetTextColor(hItem, 0x0000FF00);
//
// USER START (Optionally insert additional message handling)
case WM_KEY:
switch (((WM_KEY_INFO*)(pMsg->Data.p))->Key) {
case GUI_KEY_ESCAPE:
GUI_EndDialog(hWin, 1);
break;
case GUI_KEY_UP:
ExecSetup();//GUI_EndDialog(hWin, 0);
break;
}
break;
}
break;
// USER END
default:
WM_DefaultProc(pMsg);
break;
}
}
// USER START (Optionally insert additional public code)
void MainTask(void)
{
WM_SetCreateFlags(WM_CF_MEMDEV);
GUI_Init();
hWin_main = GUI_CreateDialogBox(_aDialogCreate1, GUI_COUNTOF(_aDialogCreate1), &_cbDialog1, WM_HBKWIN, 0, 0);
while(1)
{//GUI_ExecDialogBox(_aDialogCreate1, GUI_COUNTOF(_aDialogCreate1), &_cbDialog1, 0, 0, 0);
GUI_Delay(1000);
}
}
以下是ExecSetup的代码：
