Description
I create 2 containers.
The first container has image widget inside.
The second container has 2 label widgets inside.
If I create the first container only, it can run properly.
If I create the second container only, it can run properly.
However when put them together, it occurs runtime-error.
How to solve it?
What MCU/Processor/Board and compiler are you using?
ESP32
What LVGL version are you using?
I use lvgl 7.0dev version ( old style like lvgl6.0)
What do you want to achieve?
How to solve the 2 containers can’t run togother?
What have you tried so far?
Code to reproduce
void cont_image_create(){
static lv_style_t style_cont_image;
lv_obj_t* cont_image;
lv_obj_t* image;
lv_style_copy(&style_cont_image, &lv_style_plain);
style_cont_image.body.opa = 0;
style_cont_image.body.border.width = 0;
cont_image = lv_cont_create(lv_scr_act(), NULL);
lv_cont_set_fit(cont_image, LV_FIT_TIGHT);
lv_obj_set_style(cont_image, &style_cont_image);
LV_IMG_DECLARE(pic_ironman);
image = lv_img_create(cont_image, NULL);
lv_img_set_src(image, &pic_ironman );
lv_obj_align(cont_image, NULL, LV_ALIGN_CENTER, 0,0);
}
void cont_text_create(){
static lv_style_t style_cont_text;
lv_obj_t* cont_text;
lv_obj_t* label1;
lv_obj_t* label2;
lv_style_copy(&style_cont_text, &lv_style_plain);
style_cont_text.body.opa = 0;
style_cont_text.body.border.width = 20;

style_cont_text.body.border.part = LV_BORDER_PART_LEFT;
style_cont_text.body.radius = 0;
style_cont_text.body.padding.left = 30;
style_cont_text.text.color = LV_COLOR_WHITE;

label2 = lv_label_create(cont_text, NULL);
lv_label_set_text(label1, "Iron Man");
lv_label_set_text(label2, "Adventure");
lv_obj_align(label1, NULL, LV_ALIGN_IN_TOP_LEFT, style_cont_text.body.border.width + style_cont_text.body.padding.left, 0);
lv_obj_align(label2, label1, LV_ALIGN_OUT_BOTTOM_LEFT, 0,-15);
lv_obj_align(cont_text, NULL, LV_ALIGN_CENTER, 0,0);
}
void setup() {
Serial.begin(115200); Serial.println();
...... lvgl initialize ....
cont_image_create(); // can run properly
cont_text_create(); // can run properly but if put them together, it occurs runtime error.
}
Runtime Errors
When I looked at rumtime error’s stack, it occurs at
lv_mem_free in lv_mem_realloc at lv_mem.c
