Description

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

STM32

What LVGL version are you using?

V7.0

What do you want to achieve?

change size.

What have you tried so far?

lv_obj_set_size();

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*/

lv_obj_t * label = lv_label_create(lv_scr_act(),NULL);
lv_label_set_text(label,LV_STMBOL_WARNING);
lv_obj_set_size(label,30,30);

Screenshot and/or video

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

lv_style_init(&style);
lv_style_set_text_font(&style,LV_STATE_DEFAULT,&lv_font_montserrat_28);

As you’ve discovered, labels (by default) do not allow their size to be changed using the standard functions. This is because the default long mode controls the label’s size itself.

If you do want to customize the label’s size, you can choose a different mode (like LV_LABEL_LONG_CROP or LV_LABEL_LONG_BREAK).

Thank you very much，

You want to change the lable’s size ,right?
Not the SYMBOL size.

I am trying to change the SYMBOL size on this topic. I have multiple labels that contain some of the fontAwesome special characters (LV_SYMBOL_UP, LV_SYMBOL_DOWN, LV_SYMBOL_LEFT, LV_SYMBOL_RIGHT) … I am using these as navigation indicators, but I am wanting to change the size of these symbols. Is this possible?

any update on this?
i’ve created different fonts with my symbols at different sizes, but i can’t actually use at the same time, as the variable glyph_bitmap is already defined …
Could be nice to resize without creating every time a new icon set into a new font.

You cannot. Symbols are text fonts, if you want a bigger symbol you will have to create another font with larger symbols in it.

this is now clear!Unfortunally i’m facing issue when try to use more than one custom font… :confused:
