this demo does not work for me

[nezen]

Hi kisvegabor, thanks for your work. I've been trying to display resizable custom font on run time with littlevgl and freetype on my PC Sim but no luck so far. I just simply apply this demo to littlevgl demo, the freetype part seems to work since I can get a glyph bitmap from my font, but nothing displays. Any advice for my problem would be appreciated, thanks !

Hi,

Hm, that's strange. Please enable LV_USE_LOG and LV_USE_PRINTF in lv_conf.h.

Which simulator do you use?

Hi kisvegabor, I just folllowed the guide from https://github.com/littlevgl/lv_sim_eclipse_sdl, so I should be using SDL2 on ubuntu. The simulator project works fine alone. To provide more details, I've uploaded my code snippets and logs to https://github.com/nezen/littlevgl_demo, please take a look and see if it helps, thanks !

I've tested it like this and it worked for me:

lv_freetype_init();

static lv_font_t font1;
lv_freetype_font_init(&font1, "./lv_lib_freetype/arial.ttf", 32);

static lv_style_t style1;
lv_style_copy(&style1, &lv_style_plain);
style1.text.font = &font1;

lv_obj_t * label = lv_label_create(lv_scr_act(), NULL);
lv_label_set_style(label, LV_LABEL_STYLE_MAIN, &style1);
lv_label_set_text(label, "Hello world");

Could you try it?

I'd tried but my problem still exists. Would you mind sharing all your test codes?

Update: I have updated my littlevgl version to 6.1.2 and half of the label displays, still working on it.

I've just added my code to the freetype_test branch.

freetype_test works perfectly for me, Thanks for your time!

Great! :)
