Button release signal didn't create

Hi , I meet this problem as below.
Button release signal didn’t create when you keep button down and move you finger away from button.
I set a button release callback function to do some label settings, and I also set the button press callback function. So if the button press callback function is executed, but there is no button release function executed. That seems to be some problems for my design even though all the GUIs works like this.
Is there some methods for this problem @embeddedt @kisvegabor ? Thank you for your help.


You can do it with lv_obj_set_protect(btn, LV_PROTECT_PRESS_LOST);.
