What MCU/Processor/Board and compiler are you using?
What LVGL version are you using?
What do you want to achieve?
I want adjust the spacing (padding_inner) of object (e.g. btn) in a container with LV_LAYOUT_GRID or in a btn matrix
What have you tried so far?
I have tried the function lv_obj_set_style_local_pad_all(), but it is useless!
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:
/*uint16_t left_pos_panel = 700; uint16_t top_pos_panel = 0; uint8_t padding_inner = 1; uint8_t w_btn = 60; uint8_t h_btn = 30; lv_obj_t* ctrl_panel_cont = lv_cont_create(lv_scr_act(), NULL); //lv_cont_set_layout(ctrl_panel_cont, LV_LAYOUT_GRID); lv_obj_set_pos(ctrl_panel_cont, 620, 0); lv_obj_set_size(ctrl_panel_cont, 400, 200); lv_cont_set_layout(ctrl_panel_cont, LV_LAYOUT_OFF); lv_obj_t* btnm1 = lv_btnmatrix_create(ctrl_panel_cont, NULL); lv_btnmatrix_set_map(btnm1, btnm_map); lv_obj_set_style_local_pad_all(btnm1, LV_BTNMATRIX_PART_BG , LV_STATE_DEFAULT, 1); lv_obj_set_style_local_pad_all(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DEFAULT, 1); lv_btnmatrix_set_btn_width(btnm1, 10, 2); /*Make "Action1" twice as wide as "Action2"*/ lv_btnmatrix_set_btn_ctrl(btnm1, 10, LV_BTNMATRIX_CTRL_CHECKABLE); lv_btnmatrix_set_btn_ctrl(btnm1, 11, LV_BTNMATRIX_CTRL_CHECK_STATE); lv_obj_align(btnm1, NULL, LV_ALIGN_CENTER, 0, 0); lv_obj_set_event_cb(btnm1, event_handler);*/
As the figure shows, the spacing between body of the btn_matrix and the spacing between do not be changed.
The same problem occurs in the case of buttons in a container with LV_LAYOUT_GRID which arranges the objects accroding to padding_inner. How can I modify the padding_inner to change the spacing between objects and spacing between the objects and container?
thank you very much, best wishes
