Hi man. Since many things changed from version 6 to 7, we have got many errors:

Hi,

I was planning to archive this repo because most of the content was reimplemented in lv_examples.

Although lv_settings were not reimplemented. It's because I wasn't happy with its way of working. I found it not user friendly enough so haven't spent time with it. Hopefully, some new mechanisms of LVGL will make it easier to handle these kinds of things in the future.

[HamidSaffari]

But Gabor it's so fantasy. Which one of lv_examples is the same as lv_ex_settings?!

Beside, many things have changed since the version updated to 7, is there any helper or document which tell us how we modifying our V.6 code to V.7?

[kisvegabor]

I've updated only the settings app to v7 in v7-test branch. Visually it's a little bit different due to the new themes but functionally it works here.

[HamidSaffari]

Thanks Man. I tested and It works fine. Why don't you put this "lv_settings" lib to the lv_examples repository?

[kisvegabor]

I'm not happy with the current concept of creating pages and elements. I find it too complicated and cumbersome.

I'm sure that there are better ways to achieve this but I'm working on other features now.

Hi, Gaber How can I give all objects in the settings the same defined style. for example this style:

    static lv_style_t style_btn;
    /*Create a simple button style*/
    lv_style_init(&style_btn);
    //lv_style_set_radius(&style_btn, LV_STATE_DEFAULT, 10);
    lv_style_set_bg_opa(&style_btn, LV_STATE_DEFAULT, LV_OPA_COVER);
    lv_style_set_bg_color(&style_btn, LV_STATE_DEFAULT, LV_COLOR_YELLOW);
    lv_style_set_bg_grad_color(&style_btn, LV_STATE_DEFAULT, LV_COLOR_ORANGE);
    lv_style_set_bg_grad_dir(&style_btn, LV_STATE_DEFAULT, LV_GRAD_DIR_VER);
    /*Swap the colors in pressed state*/
    lv_style_set_bg_color(&style_btn, LV_STATE_PRESSED, LV_COLOR_ORANGE);
    lv_style_set_bg_grad_color(&style_btn, LV_STATE_PRESSED, LV_COLOR_YELLOW);
    /*Add a border*/
    lv_style_set_border_color(&style_btn, LV_STATE_DEFAULT, LV_COLOR_BLACK);
    lv_style_set_border_opa(&style_btn, LV_STATE_DEFAULT, LV_OPA_70);
    lv_style_set_border_width(&style_btn, LV_STATE_DEFAULT, 4);
    /*Different border color in focused state*/
    lv_style_set_border_color(&style_btn, LV_STATE_FOCUSED | LV_STATE_PRESSED, LV_COLOR_YELLOW);
    /*Set the text style*/
    lv_style_set_text_color(&style_btn, LV_STATE_DEFAULT, LV_COLOR_BLACK);
    /*Make the button smaller when pressed*/
    lv_style_set_transform_height(&style_btn, LV_STATE_PRESSED, -2);
    lv_style_set_transform_width(&style_btn, LV_STATE_PRESSED, -5);

    lv_obj_add_style(setting_btn, LV_BTN_PART_MAIN, &style_btn); 

to all objects.

The easiest way to add it to lv_settings.c direcly. E.g. here: https://github.com/lvgl/lv_apps/blob/master/src/lv_settings/lv_settings.c#L367
