emWin: 键盘EDIT自动获取点击EDIT框里的值并修改
1、数字软键盘修改数据，先上照片：
2、实现如下：
typedef struct tag_mdfKey
{
u8 flag_ent; //确认标志
u32 id_press; //修改控件:ID
char mdf_buff[30]; //修改数据缓冲区
}KPad_MDF;
static WM_MESSAGE kp_Msg;
KPad_MDF kpad_mdf; //数字键盘修改结构体变量
//数字小键盘：回调函数：
/*

*/
static void _cbDialogNumPad(WM_MESSAGE * pMsg) {
GUI_RECT r;
int i, NCode, Id, Pressed = 0;
WM_HWIN hDlg, hItem;
hDlg = pMsg->hWin;
switch (pMsg->MsgId) {
case KEYPAD_UPDATE_MSG: //数字小键盘: 更新数据消息
if(kpad_mdf.id_press>0){
hItem = WM_GetDialogItem(hDlg, GUI_ID_EDIT1);
EDIT_SetText(hItem,kpad_mdf.mdf_buff);
}else{

EDIT_SetText(hItem,"");
}
WM_SetFocus(hItem); //聚焦于小键盘上的EDIT编辑框
break;
