Description

What MCU/Processor/Board and compiler are you using?

esp32

What LVGL version are you using?

8.2

What do you want to achieve?

below is the code I write
I found that the height of text “list title” is so small
is there anyway to set is high

What have you tried so far?

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

void my_demo(void)
{
	lv_obj_t * obj_list lv_list_creat(lv_scr_act());
	lv_obj_t *_title = lv_list_add_text(obj_list, "Title");
	btn = lv_list_add_btn(list1, LV_SYMBOL_FILE, "New");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(list1, LV_SYMBOL_DIRECTORY, "Open");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(list1, LV_SYMBOL_SAVE, "Save");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(list1, LV_SYMBOL_CLOSE, "Delete");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(list1, LV_SYMBOL_EDIT, "Edit");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
}

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

Hi @Kingwulin ,

To change the text height you would need to set a bigger font size.

So taking your example it would be something like this:

void my_demo(void)
{
	lv_obj_t *btn;
	lv_obj_t *obj_list = lv_list_create(lv_scr_act());

	lv_obj_t *_title = lv_list_add_text(obj_list, "Title");

    /* Increase size of font for the list */
	lv_obj_set_style_text_font(obj_list,  &lv_font_montserrat_20, LV_PART_MAIN);

	btn = lv_list_add_btn(obj_list, LV_SYMBOL_FILE, "New");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(obj_list, LV_SYMBOL_DIRECTORY, "Open");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(obj_list, LV_SYMBOL_SAVE, "Save");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(obj_list, LV_SYMBOL_CLOSE, "Delete");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
    btn = lv_list_add_btn(obj_list, LV_SYMBOL_EDIT, "Edit");
    lv_obj_add_event_cb(btn, event_handler, LV_EVENT_CLICKED, NULL);
}

I hope that helps…

Kind Regards,

Pete
