STEMWIN创建一个提示对话框

用guibuilder创建好对话框

WM_MESSAGE 的元素

pMsg->MsgId

static void _cbDialog(WM_MESSAGE * pMsg) 
{
    WM_HWIN hItem;
    int     NCode;
    int     Id;
    WM_MESSAGE Msg;

    switch (pMsg->MsgId) 
    {
        case WM_INIT_DIALOG:
            //初始化FRAMEWIN
            hItem = pMsg->hWin;
            FRAMEWIN_SetText(hItem, "EDIT USER");
            FRAMEWIN_SetTextAlign(hItem, GUI_TA_HCENTER | GUI_TA_VCENTER);
            FRAMEWIN_SetFont(hItem, GUI_FONT_16B_ASCII);

            //初始化EDIT  显示hello word
            hItem = WM_GetDialogItem(pMsg->hWin, GUI_ID_EDIT0);
            EDIT_EnableBlink(hItem, 500, 1);
            EDIT_SetText(hItem, "Hello Word!");
            EDIT_SetFont(hItem, &GUI_Font20_ASCII);
            EDIT_SetTextAlign(hItem, GUI_TA_LEFT | GUI_TA_VCENTER);

            break;

        case WM_NOTIFY_PARENT:
            Id    = WM_GetId(pMsg->hWinSrc);
            NCode = pMsg->Data.v; //得到数据值 也就是动作类型
            switch(Id) 
            {
                case GUI_ID_EDIT0:  //EDIT控件通知消息
                    switch(NCode) //判断动作类型
                    {
                        case WM_NOTIFICATION_CLICKED:
                            break;
                        case WM_NOTIFICATION_RELEASED:
                            break;
                        case WM_NOTIFICATION_VALUE_CHANGED:
                            break;
                    }
                    break;

                case GUI_ID_OK:
                    switch(NCode) 判断动作类型
                    {
                        case WM_NOTIFICATION_CLICKED:
                            break;

                        case WM_NOTIFICATION_RELEASED:
                            Msg.MsgId=WM_APP_SHOW_TEXT;
                            Msg.hWinSrc=pMsg->hWin;
                            WM_SendMessage(WM_HBKWIN,&Msg);
                            break;

                    }       
            }
            break;
    default:
        WM_DefaultProc(pMsg);
        break;
    }
}

pMsg->MsgId=WM_INIT_DIALOG

初始化标题栏 ：包括标题文本内容，字体大小，对齐方式##

case WM_INIT_DIALOG:
            //初始化FRAMEWIN
            hItem = pMsg->hWin;
            FRAMEWIN_SetText(hItem, "EDIT USER");//内容
            FRAMEWIN_SetTextAlign(hItem, GUI_TA_HCENTER | GUI_TA_VCENTER);//对齐方式
            FRAMEWIN_SetFont(hItem, GUI_FONT_16B_ASCII);
            //初始化EDIT  设置字体

初始化里面的提示内容

下面这个 函数很重要
WM_GetDialogItem(pMsg->hWin, GUI_ID_EDIT0);
得到某个控件的窗口值

代码如下

//初始化EDIT
            hItem = WM_GetDialogItem(pMsg->hWin, GUI_ID_EDIT0);    //GUI_ID_EDITO在程序上面的资源表中找的到
            EDIT_EnableBlink(hItem, 500, 1);  //启用光标
            EDIT_SetText(hItem, "Hello Word!"); //文本内容
            EDIT_SetFont(hItem, &GUI_Font20_ASCII);//文本大小
            EDIT_SetTextAlign(hItem, GUI_TA_LEFT | GUI_TA_VCENTER);//对齐方式

pMsg->MsgId=WM_NOTIFY_PARENT

对话框中有控件（例如：按钮）发生了动作
NCode = pMsg->Data.v pMsg->Data.v的值如下

代码如下

    case WM_NOTIFY_PARENT:
            Id    = WM_GetId(pMsg->hWinSrc);//得到控件ID号判断是哪个按钮或者哪个小控件发生了动作
            NCode = pMsg->Data.v;   //
            switch(Id) 
            {
                case GUI_ID_EDIT0:  //EDIT控件通知消息
                    switch(NCode) 
                    {
                        case WM_NOTIFICATION_CLICKED:
                            break;
                        case WM_NOTIFICATION_RELEASED:
                            break;
                        case WM_NOTIFICATION_VALUE_CHANGED:
                            break;
                    }
                    break;
                case GUI_ID_OK:  //**OK按钮发生了动作**
                    switch(NCode)
                    {
                        case WM_NOTIFICATION_CLICKED:
                            break;

                    }       
            }
            break;
            // #define WM_APP_SHOW_TEXT     (WM_USER +0)
//M_USER 应用程序可使用 WM_USER 常数来定义私人消息，通常形式为
//WM_USER+X，其中 X 为整数值。

消息（按钮）发送完后，接下来就是处理消息

//背景窗口的回调函数
static void _BkCallback(WM_MESSAGE *pMsg)
{
    static WM_HWIN hWin;
    static WM_HWIN hEdit;
    static U8 text;
    char   buffer[TEXT_MAXLEN];
    switch(pMsg->MsgId)
    {
        case WM_PAINT:
            GUI_SetBkColor(GUI_DARKGRAY);
            GUI_Clear();
            GUI_SetFont(&GUI_Font24_ASCII);
            GUI_DispStringHCenterAt("WIDGET_Edit - Sample", 160, 5);
            GUI_SetFont(&GUI_Font8x16);
            if (text) 
            {
                hEdit=WM_GetDialogItem(DialoghWin,GUI_ID_EDIT0);
                GUI_DispStringHCenterAt("The string you have modified is:", 160, 90);
                EDIT_GetText(hEdit, buffer, TEXT_MAXLEN);
                GUI_DispStringHCenterAt(buffer, 160, 110);
            } 
            else
            {   
                GUI_DispStringHCenterAt("Use keyboard to modify string...", 160, 90);
            }
            break;  
        case WM_APP_SHOW_TEXT:
            hWin=pMsg->hWinSrc;
            WM_HideWindow(hWin);    //隐藏对话框
            text=1;
            WM_InvalidateWindow(WM_HBKWIN); //背景窗口无效
            WM_CreateTimer(WM_HBKWIN,0,3000,0); //定时处理
            break;
        case WM_TIMER:  //时间到了接收到了定时的消息做出相应的处理
            text=0;
            WM_InvalidateWindow(WM_HBKWIN);
            WM_ShowWindow(hWin);
            break;
        default:
            WM_DefaultProc(pMsg);
            break;
    }   
}

代码中的case ：WM_APP_SHOW_TEXT

这正是我们之前所发送的自定义消息

隐藏对话框

WM_HideWindow(hWin); //隐藏对话框

显示对话框

WM_ShowWindow(hWin);
