c - STemWin STM32F746G-DISCO 与小部件库

Question

我正在使用 STM32 的新板，并从 GUIBuilder 中添加了简单的页面，从包含的软件到库。当我运行我的代码时，例如单击滑块小部件时，我遇到了一些错误。滑块更改了他的值，但是当我单击屏幕的其他部分（未安装在小部件中）时，他的值仍然会更改。整个屏幕只关注这个小部件。我使用 STM32 为这个开发套件提供的 CubeF7 的 LCD 设置。我还包括了负责我的窗口的部分代码，这些代码不起作用。也许有人有同样的问题，或者我使用了错误的文件。

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

  switch (pMsg->MsgId) {
  case WM_INIT_DIALOG:
    //
    // Initialization of 'Text'
    //
    hItem = WM_GetDialogItem(pMsg->hWin, ID_TEXT_0);
    TEXT_SetTextAlign(hItem, GUI_TA_LEFT | GUI_TA_VCENTER);
    TEXT_SetFont(hItem, GUI_FONT_32B_1);
    // USER START (Optionally insert additional code for further widget initialization)
    // USER END
    break;
  case WM_NOTIFY_PARENT:
    Id    = WM_GetId(pMsg->hWinSrc);
    NCode = pMsg->Data.v;
    switch(Id) {
    case ID_SLIDER_0: // Notifications sent by 'Slider'
      switch(NCode) {
      case WM_NOTIFICATION_CLICKED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      case WM_NOTIFICATION_RELEASED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      case WM_NOTIFICATION_VALUE_CHANGED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      // USER START (Optionally insert additional code for further notification handling)
      // USER END
      }
      break;
    case ID_BUTTON_0: // Notifications sent by 'Button'
      switch(NCode) {
      case WM_NOTIFICATION_CLICKED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      case WM_NOTIFICATION_RELEASED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      // USER START (Optionally insert additional code for further notification handling)
      // USER END
      }
      break;
    case ID_BUTTON_1: // Notifications sent by 'Button'
      switch(NCode) {
      case WM_NOTIFICATION_CLICKED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      case WM_NOTIFICATION_RELEASED:
        // USER START (Optionally insert code for reacting on notification message)
        // USER END
        break;
      // USER START (Optionally insert additional code for further notification handling)
      // USER END
      }
      break;
    // USER START (Optionally insert additional code for further Ids)
    // USER END
    }
    break;
  // USER START (Optionally insert additional message handling)
  // USER END
  default:
    WM_DefaultProc(pMsg);
    break;
  }
