emwin定时器的问题,有图有真相。。

我想做的事是这样的：创建一个窗口，上面有一个进度条PROGBAR，用WM定时器来更新它的数值，1秒让它增加1。想要的效果是这样的：




#include "DIALOG.h"

/*********************************************************************
*
*       Defines
*
**********************************************************************
*/
#define ID_WINDOW_0     (GUI_ID_USER + 0x00)
#define ID_PROGBAR_0     (GUI_ID_USER + 0x01)

int Flag = 0;
// USER START (Optionally insert additional defines)
// USER END

/*********************************************************************
*
*       Static data
*
**********************************************************************
*/

// USER START (Optionally insert additional static data)
// USER END

/*********************************************************************
*
*       _aDialogCreate
*/
static const GUI_WIDGET_CREATE_INFO _aDialogCreate[] = {
  { WINDOW_CreateIndirect, "Window", ID_WINDOW_0, 0, 0, 320, 240, 0, 0x0, 0 },
  { PROGBAR_CreateIndirect, "Progbar", ID_PROGBAR_0, 76, 89, 155, 38, 0, 0x0, 0 },
  // USER START (Optionally insert additional widgets)
  // USER END
};

/*********************************************************************
*
*       Static code
*
**********************************************************************
*/

// USER START (Optionally insert additional static code)
// USER END

/*********************************************************************
*
*       _cbDialog
*/
static void _cbDialog(WM_MESSAGE * pMsg)
{
  WM_HWIN hItem;
  // USER START (Optionally insert additional variables)
  // USER END

  switch (pMsg->MsgId)
  {
    case WM_INIT_DIALOG:

    // Initialization of 'Window'

    hItem = pMsg->hWin;
    WINDOW_SetBkColor(hItem, GUI_LIGHTBLUE);

    // Initialization of 'Progbar'

    hItem = WM_GetDialogItem(pMsg->hWin, ID_PROGBAR_0);
    PROGBAR_SetFont(hItem, GUI_FONT_6X8);

找到问题了，定时器创建的问题，把WM_HWIN CreateWindow(void)函数注释掉；在void MainTask(void)中添加：

WM_HWIN hWin;

  hWin = GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, WM_HBKWIN, 0, 0);

将hTimer = WM_CreateTimer(WM_HBKWIN,0,1000,0);改为hTimer = WM_CreateTimer(hWin,0,1000,0);

就搞定了

代码竟然木有显示全。。。

追加！！！

/*********************************************************************

  // USER END

  switch (pMsg->MsgId)
  {
    case WM_INIT_DIALOG:
   
    // Initialization of 'Window'
   
    hItem = pMsg->hWin;
    WINDOW_SetBkColor(hItem, GUI_LIGHTBLUE);
   
    // Initialization of 'Progbar'
   
    hItem = WM_GetDialogItem(pMsg->hWin, ID_PROGBAR_0);
    PROGBAR_SetFont(hItem, GUI_FONT_6X8);
        PROGBAR_SetTextColor(hItem,0,GUI_BLACK);
        PROGBAR_SetMinMax(hItem,0,100);

    break;

        case WM_TIMER:
        hItem = WM_GetDialogItem(pMsg->hWin, ID_PROGBAR_0);
        WM_RestartTimer(pMsg->Data.v,1000);

        Flag ++;
        if(Flag == 100)
        {
          Flag = 0;
        }
        GUI_Delay(200);
        break;

        default:
    WM_DefaultProc(pMsg);
    break;
  }
}
