Text poistion in lv_ta

[BenQoo]

I have a question. If I would like to adjust the position of text in lv_ta, which vpad and hpad should I take?

• Style of lv_ta
• Style of scrollbar style_sb from lv_page_get_style_sb(ta)

I made some try. I use ptask to change vpad periodically.
I set vpad on style of lv_ta, it worked on the first time call lv_obj_set_style(ta, &ta_style), but it didn't work on the second time or set style to the other new lv_style_t.
About style_sb, It's no effect by changing its vpad.

Thanks!

It really doesn't work properly. I will fix it on Monday. Until that please try this: lv_obj_set_style(lv_page_get_scrl(ta), &style) it will set the style of the transparent scrollable part of text area. Use LV_STYLE_TRANSP_TIGHT as starting point.

vpad and hpad now do not affect the scrollbar position but it is a good idea to do that!

Now the label's position should be affected by hpad and vpad.
Can you test it?

How do you imagine the scrollbar and hpad/vpad relationship?

No problem.
After testing, It works now, thank you!

Sorry, I'm not familiar with them. I guess it can change hpad/vpad to adjust the position of scrollbar.

I'm happy that it's working! :)

I will figure out something for scrollbar.

In beta scrollbar positions are affected by style.body.padding.hor and style.body.padding.hor.
(Please update you misc_conf.h and lv_conf.h from misc_conf_templ.h and lv_conf_templ.h)

Like this:

    static lv_style_t sb_style;
    lv_style_copy(&sb_style, &lv_style_plain_color);
    sb_style.body.padding.hor = -15;
    sb_style.body.padding.ver = 15;

    lv_obj_t *page = lv_page_create(lv_scr_act(), NULL);
    lv_page_set_style(page, LV_PAGE_STYLE_SB, &sb_style);
    lv_page_set_sb_mode(page, LV_SB_MODE_ON);
    lv_page_set_scrl_fit(page, true, true);
    lv_obj_set_size_scale(page, 100, 200);
    lv_obj_set_pos_scale(page, 10, 10);

    lv_obj_t *label = lv_label_create(page, NULL);
    lv_label_set_text(label, "long long lines\n\n"
                             "to shows the\n\n"
                             "scrollbars'\n\n"
                             "position.\n\n"
                             "Some dummy text\n\n"
                             "Some dummy text\n\n"
                             "Some dummy text\n\n");
