Introduction

lv_chinese_ime is a custom component written on the basis of lv_keyboard (the creation interface is: lv_chinese_ime_create(lv_obj_t *parent)); ), it is no different from lv_keyboard, but the function of supporting Chinese input method (Pinyin) is added.

So we call it: Support Chinese input method LVGL keyboard (lv_keyboard) widget enhancement plugin.

Normally, as long as lvgl can run in an environment lv_chinese_ime can also run! There are two main influencing factors: the size of the font file used and the size of the thesaurus used.

lv_chinese_ime is very simple to use, and the subsequent custom expansion functions are also very convenient, so stay tuned for more functions.

Usage

  1. Clone this repository: https://github.com/100askTeam/lv_chinese_ime.git
  2. The lv_chinese_ime directory should be next to the lvgl directory in your project. Similarly to lv_conf.h there is a configuration file for the examples too. It is called lv_chinese_ime_conf.h.
  3. Copy lv_chinese_ime/lv_chinese_ime_conf_template.h next to lv_chinese_ime directory
  4. Rename it to lv_chinese_ime_conf.h
  5. Change the first #if 0 to #if 1 to enable the file's content
  6. Enable or Disable function
  7. To prepare a font file or thesaurus file, read more: lv_chinese_ime/test/README.md
  8. Use example:
/*declare font*/
LV_FONT_DECLARE(lv_font_source_han_sans_bold_14);

static void ta_event_cb(lv_event_t * e)
{
    lv_event_code_t code = lv_event_get_code(e);
    lv_obj_t * ta = lv_event_get_target(e);
    lv_obj_t * kb = lv_event_get_user_data(e);

    if(code == LV_EVENT_FOCUSED) {
        if(lv_indev_get_type(lv_indev_get_act()) != LV_INDEV_TYPE_KEYPAD) {
            lv_keyboard_set_textarea(kb, ta);
            lv_obj_set_style_max_height(kb, LV_HOR_RES * 2 / 3, 0);
            lv_obj_clear_flag(kb, LV_OBJ_FLAG_HIDDEN);
            lv_obj_scroll_to_view_recursive(ta, LV_ANIM_OFF);
        }
    }
    else if(code == LV_EVENT_READY || code == LV_EVENT_CANCEL) {
        lv_obj_add_flag(kb, LV_OBJ_FLAG_HIDDEN);
        lv_obj_clear_state(ta, LV_STATE_FOCUSED);
        lv_indev_reset(NULL, ta);   /*To forget the last clicked object to make it focusable again*/
    }
}

void your_test_function(void)
{
    lv_obj_t * kb = lv_chinese_ime_create(lv_scr_act());
    lv_chinese_ime_set_text_font(&lv_font_source_han_sans_bold_14, 0);   // set font
    //lv_chinese_ime_set_dict(your_dict); // Use a custom thesaurus. If it is not set, the built-in thesaurus will be used


    /* ta1 */
    lv_obj_t * ta1 = lv_textarea_create(lv_scr_act());
    lv_obj_set_style_text_font(ta1, &lv_font_source_han_sans_bold_14, 0);   // set font
    lv_obj_align(ta1, LV_ALIGN_TOP_LEFT, 10, 10);

    lv_keyboard_set_textarea(kb, ta1);

    lv_obj_add_event_cb(ta1, ta_event_cb, LV_EVENT_ALL, kb);

    /* ta2 */
    lv_obj_t * ta2 = lv_textarea_create(lv_scr_act());
    lv_obj_set_style_text_font(ta2, &lv_font_source_han_sans_bold_14, 0);   // set font
    lv_obj_align_to(ta2, ta1,LV_ALIGN_OUT_RIGHT_MID, 10, 0);

    lv_obj_add_event_cb(ta2, ta_event_cb, LV_EVENT_ALL, kb);
}

NOTE

  • Only one lv_chinese_ime can exist in a project at the same time.
  • When lv_chinese_ime is not needed, please use lv_chinese_ime_del to delete it.
  • After deleting lv_chinese_ime normally, you can recreate the usage through the [above](# Usage) usage example..
