    • Does DROPDOWN_SetSel() always trigger a WM_NOTIFICATION_SEL_CHANGED?

      Hello,

      I have some dropdown menus which I fill with the last settings using DROPDOWN_SetSel in WM_INIT_DIALOG. After this a WM_NOTIFICATION_SEL_CHANGED is triggered. Is it possible to avoid this and notify only changes by touch inputs?

    • Hello Jan,

      unfortunately this is not possible without changing the emWin code. The only way would be to set a global flag always when calling DROPDOWN_SetSel() and instantly clearing the flag when reaching the WM_NOTIFY_PARENT case. When the flag would be set, the WM_NOTIFY_PARENT would be ignored.

      Best regards,

      Florian

    • Thank you, Florian. Setting a global flag was also my workaround. Maybe some blocking feature for notifications would be an idea for future improvements. For me it was disturbing that I always got a beep tone, which I trigger by the notification, after SetSel but I wanted this tone only at manual inputs.
