Please find the code below.

  2. IDC_HELP, IDC_IBEAM, IDC_ICON, IDC_NO, IDC_SIZE, IDC_SIZEALL, \

我已经进行了一些改进，以使其更加简化。

英文:

I've made some improvements to be more streamlined

  1. from win32con import IDC_APPSTARTING, IDC_ARROW, IDC_CROSS, IDC_HAND, \
  2. IDC_HELP, IDC_IBEAM, IDC_ICON, IDC_NO, IDC_SIZE, IDC_SIZEALL, \
  3. IDC_SIZENESW, IDC_SIZENS, IDC_SIZENWSE, IDC_SIZEWE, IDC_UPARROW, IDC_WAIT
  5. from win32gui import LoadCursor, GetCursorInfo
  7. DEFAULT_CURSORS = {
  8.     LoadCursor(0, IDC_APPSTARTING): 'appStarting',
  9.     LoadCursor(0, IDC_ARROW): 'Arrow', LoadCursor(0, IDC_CROSS): 'Cross',
  10.     LoadCursor(0, IDC_HAND): 'Hand', LoadCursor(0, IDC_HELP): 'Help',
