I am running Windows VS V8.x,x Simulator on Win10. Been experimenting with buttons, I cant understand what controls when the blue focus outline that appears around a button ? It seems unpredictable to me.
Taking the button example lv_example_btn_1.c file. The top button has the focus and draws the outline, clicking on that button retains the focus outline as expected. If I click on the toggle button tjhat doesnt show the focus outline, and then if I click back on the top button that no longer shows the focus outline. The focus outline wont come back until i re-run the example.
Q1) Is this expected behavour, what is the logic for when a focus outline is drawn ?
Q2) I tried to turn off the focus outline, but couldnt get it to work. Neither of these lines turn it off
lv_obj_clear_state(btn1, LV_STATE_FOCUSED); lv_obj_clear_flag(btn1, LV_OBJ_FLAG_CLICK_FOCUSABLE);
Searching around I found this suggestion
However that function seems to be gone in V8 and I couldnt find an equivalent function.
Any help on how to turn the outline off please ?
