我创建窗口如下：

  { WINDOW_CreateIndirect, "Window_S4", ID_WINDOW_3, 0, 80, 310, 180, 0, 0x0, 0 },
  { EDIT_CreateIndirect, "Edit_old", ID_EDIT_0, 20, 60, 110, 30, 0, 0x64, 0 },
  { EDIT_CreateIndirect, "Edit_PS1", ID_EDIT_1, 20, 110, 110, 30, 0, 0x64, 0 },
  { BUTTON_CreateIndirect, "确认",           ID_BUTTON_0, 45, 145, 60,25, 0,0},
  { EDIT_CreateIndirect, "Edit_old", ID_EDIT_2, 175, 60, 110, 30, 0, 0x64, 0 },
  { EDIT_CreateIndirect, "Edit_PS1", ID_EDIT_3, 175, 110, 110, 30, 0, 0x64, 0 },
  { BUTTON_CreateIndirect, "确认",           ID_BUTTON_1, 200, 145, 60,25, 0,0},
   
  { TEXT_CreateIndirect, "登录密码", ID_TEXT_0, 40, 10, 68, 20, 0, 0x64, 0 },//Change password
  { TEXT_CreateIndirect, "原密码", ID_TEXT_1, 20, 40, 60, 20, 0, 0x64, 0 },//OLD
  { TEXT_CreateIndirect, "新密码", ID_TEXT_2, 20, 92, 60, 20, 0, 0x64, 0 },//1

  { TEXT_CreateIndirect, "控制密码", ID_TEXT_3, 192, 10, 165, 20, 0, 0x64, 0 },//Change password
  { TEXT_CreateIndirect, "原密码", ID_TEXT_4, 175,40, 60, 20, 0, 0x64, 0 },//OLD
  { TEXT_CreateIndirect, "新密码", ID_TEXT_5, 175,92, 60, 20, 0, 0x64, 0 },//1
焦点按照以上顺序切换，但当焦点在BUTTON时，按返回按键将焦点聚焦到本窗口，在聚焦到EDIT时，
发现焦点还在BUTTON没有退出焦点，但是没有聚焦框，TAB无法上下切换，如何退出焦点可以TAB切换？

这个不太清楚了，还没有测试过退出焦点的情况。
