c++ - Correct mouse event order on a doubleclick -

-

what's correct order of events should see when user double click?

  • down - - down - doubleclick - up
  • down - - doubleclick - down - up
  • down - - doubleclick - up

is platform specific? how should work in windows?

for windows api - variant 3:

only windows have cs_dblclks style can receive wm_lbuttondblclk messages, system generates whenever user presses, releases, , again presses left mouse button within system's double-click time limit. double-clicking left mouse button generates sequence of 4 messages: wm_lbuttondown, wm_lbuttonup, wm_lbuttondblclk, , wm_lbuttonup.
