Request TextArea when create by copy parameter, the new one is copied placeholder too

Feature request
1

When a new TextArea is created by copying from the old new

lv_obj_t new_ta = lv_ta_create(lv_scr_act(), old_ta);

The new one has the same with the old one’s placeholder too.

I quickly added a trivial implementation of this feature to the ta_placeholder_copy branch. Can you test it? If it works it can be merged into dev-6.1.

It should be reposition between these lines ?

From

       if(copy_ext->one_line) lv_ta_set_one_line(new_ta, true);
       if(copy_ext->placeholder != NULL)
            ext->placeholder = lv_label_create(new_ta, copy_ext->placeholder);
        else
            ext->placeholder = NULL;

To

       if(copy_ext->placeholder != NULL)
            ext->placeholder = lv_label_create(new_ta, copy_ext->placeholder);
        else
            ext->placeholder = NULL;

       if(copy_ext->one_line) lv_ta_set_one_line(new_ta, true);

Because of “lv_ta_set_one_line” should be effect to the not-null placeholder too?

Another issue,
when I created password_ta as a password-mode TextArea.
And I copied the old password_ta to the new one (password_ta2)
as the following code :

  lv_obj_t *password_ta = lv_ta_create(lv_scr_act(), NULL);
    lv_ta_set_pwd_mode(password_ta, true);
    lv_ta_set_text(password_ta, "1234567890");
    lv_ta_set_placeholder_text(password_ta, "Password");
    lv_obj_set_width(password_ta, 240-12);
    lv_obj_set_pos(password_ta, 6,6);

  lv_obj_t *password_ta2 = lv_ta_create(lv_scr_act(), password_ta);
  
  lv_obj_t *kb = lv_kb_create(lv_scr_act(), NULL);
    lv_kb_set_ta(kb, password_ta2);
    lv_obj_set_size(kb,240,180);
    lv_obj_align(kb, NULL, LV_ALIGN_IN_BOTTOM_MID,0,0);

The password_ta2’s text is already copied from password_ta ( = 1234567890 ).
However it shows 1234567890, it doesn’t show **********
How to show ********** by default after copying password-mode TextArea?

Thank you.

Found at :

I tried to change from

ext->pwd_mode          = copy_ext->pwd_mode;

To

ext->pwd_mode          = copy_ext->pwd_mode;
if(ext->pwd_mode != 0) pwd_char_hider( new_ta);

It’s ok now. The new copied one is already shown as **********.

I updated the ta_placeholder_copy branch with your change; does it work properly now?

9

The new copied one is already shown as ********** .
But when typing by touch-keyboard , it occurs error at runtime.

10

Yes, I saw your other post.

11

Probably it’s because allocating ext->pwd_tmp is also missing from the copy.
