Hi, guys,

I'm using emwin 5.20 on 1788 within freertos, and the hid device is usb keyboard. Now, I face a problem about the MENU. I create the gui by GUIBuilder, The system is dying when a put a menu widget on the windows, and switch the focus by TAB key on the menu. It seemed that the system is broken, cause that the led indicator doesn't work any more.

I tryed several time with diffent numbers of the widgets. the fault is pointed to the MENU.

is it a bug? or anything I forgot to do, but I think the menu should be same as the other widgets.

Please tell me if anyone know the reason.

Thank you.

Alex.

Finaly, I find the problem:

case WM_MENU:
switch (pData->MsgType)
{
case MENU_ON_INITMENU:
break;
case MENU_ON_ITEMSELECT:
break;
default:
WM_DefaultProc(pMsg);
break;
}
break;
WM_DefaultProc(pMsg); MUST be called in the defualt route.
