Theme - distinct style for the same lv_obj_class

[bruno]

Hi @kdluzynski, To achieve what you want I think you have to create your own class for each type of button to diferenciate it in the apply theme callback using lv_obj_check_type() function. If you use LVGL pro you can use subjects to change bind styles and create themes.

This can help you create your own class:

Creating a custom widget

Hello all, is there any how-to on the creation of a custom widget in C? I only have found an example for MicroPython, which does not really help. To start, I have copied the code from lv_led.[ch] into my project, renamed all to lv_led_rect and call it from my application code. Apart from this, I have not changed anything. The code compiles and is linked properly. Both constructor and event handler are called. But: nothing happens on the screen. Does the new widget require some kind of regist…

Or instead of two widgets you can create just one button and add custom flags/properties to change its types between red/blue on the theme apply callback
