Setting dropdown focused border color

Micropython
1

I am unable to set the border color of the pressed state of a dropdown in the current MP/LVGL. Setting the background works as does setting the border for the default and focused states. But this has no effect:

lv_obj.set_style_local_border_color(lv.dropdown.PART.MAIN, lv.STATE.PRESSED, mycolor)

Is this a bug or am I missing something obvious?

I’m not sure.
It’s probably not Micropython specific.

@kisvegabor, @embeddedt - Any idea?

It’s not really a bug but a counter-intuitive behavior in the material theme (I assume you are used it).

The material theme defines the border color in pressed, focused and pressed | focused. If you click the dropdown it will go to pressed | focused state and the pressed | focused color from theme theme will overwrite your pressed color.

You can do 2 things:

  1. Add the LV_THEME_MATERIAL_FLAG_NO_FOCUS in lv_conf.h to disable focused styles. I’ve pushed a fix for it to the release/v7 branch of lvgl. Please, be sure to update to it.
  2. Add border color in pressed and pressed | focused states too
