Spinbox callback, close window with long press after exit editing (using encoder)

How-to

Hello!

I’m facing following problem: I have a submenu in a window which activated by switching the hidden attribute. My project uses an encoder with up/down/enter. The window is closed by long-pressing the enter button, which coincidentally is also releasing the focus of the inner elements of the spinbox.

User flow would be: select spinbox -> press enter -> change value 1 -> press enter -> change value 2 etc. … or -> long press enter to deselect the spinbox and be able to navigate the menu again, or -> long press again to close the menu and return to the previous page.

The problem is, the only events arriving at the spinbox event handler are pressed, short_clicked, clicked, released, focused, defocused, and value changed.

I have been trying to just store the previous event and see if there is a unique event combination if I apply the user flow but there seems to be none. Then I thought, well lets look into the code of spinbox and see where the event is dispatched, maybe I can inject the event I am looking for, but in lv_spinbox.c there is no event being dispatched.

now I am confused and felt like it’s best to ask here, maybe somebody has a pointer for me where to look or an idea how to implement this differently.

thanks!

Hi,

It’s because the spinbox changes between navigating and edit mode on long press. However, you get a LV_EVENT_FOCUSED event on navigate/edit change. To decide in which state we are now you can use lv_group_get_editing(lv_obj_get_group(spinbox))
