Description
Hi,I encountered a problem.Before the screen is rotated, the coordinates of the button are obtained, and clicking the button can respond.
After the screen rotates, the coordinates remain unchanged and there is no response when clicking the button.
What MCU/Processor/Board and compiler are you using?
Xilinx mpsoc
What LVGL version are you using?
8.3.3
What do you want to achieve?
I want to know how to set the clicked coordinates after rotating the screen
What have you tried so far?
Before the screen is rotated, the coordinates of the button are obtained, and clicking the button can respond
After the screen rotates, the coordinates remain unchanged and there is no response when clicking the button
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:
static lv_disp_drv_t disp_drv_1;
lv_disp_drv_init(&disp_drv_1);
disp_drv_1.draw_buf = &disp_inch7_buf;
disp_drv_1.flush_cb = fbdev_flush_1;
disp_drv_1.hor_res = 280;
disp_drv_1.ver_res = 1424;
disp_drv_1.antialiasing = 1;
disp_drv_1.sw_rotate=1;
disp_1 = lv_disp_drv_register(&disp_drv_1);
lv_disp_set_rotation(disp_1, LV_DISP_ROT_270);
const lv_point_t points_array_1[] = { {60,60},{712,140},{(86+178*2),785},{(86+178*3),785},{(86+178*4),785},{(86+178*5),785},{(86+178*6),785},{(86+178*7),785}};
static lv_indev_drv_t indev_button_1;
lv_indev_drv_init(&indev_button_1); /*Basic initialization*/
indev_button_1.type = LV_INDEV_TYPE_BUTTON;
indev_button_1.disp=disp_1;
indev_button_1.read_cb = button_read_1;
lv_indev_t * button_indev_1 = lv_indev_drv_register(&indev_button_1);
lv_indev_set_button_points(button_indev_1, points_array_1);
static void event_cb(lv_event_t * e)
{
lv_indev_t* indev = lv_indev_get_act(); //获取活动界面输入设备
lv_point_t point;
lv_indev_get_point(indev, &point);
printf("x=%d,y=%d\n",point.x,point.y);
LV_LOG_USER("Clicked");
static uint32_t cnt = 1;
lv_obj_t * btn = lv_event_get_target(e);
lv_obj_t * label = lv_obj_get_child(btn, 0);
lv_label_set_text_fmt(label, "%"LV_PRIu32, cnt);
cnt++;
}
void first_1(lv_disp_t * disp,const char *text,int choice)
{
cur_scr_act = lv_disp_get_scr_act(disp);
lv_obj_clean(cur_scr_act);
lv_obj_set_style_bg_color(cur_scr_act,lv_color_make(64,64,64),0);
lv_obj_clear_flag(cur_scr_act,LV_OBJ_FLAG_SCROLLABLE);
lv_obj_t * btn = lv_btn_create(cur_scr_act);
lv_obj_set_size(btn, 100, 100);
lv_obj_align(btn,LV_ALIGN_TOP_LEFT,10,10);
lv_obj_add_event_cb(btn, event_cb, LV_EVENT_CLICKED, NULL);
lv_obj_t * label = lv_label_create(btn);
lv_label_set_text(label, "Click me!");
lv_obj_center(label);
lv_obj_update_layout(btn);
printf("btn_x=%d,btn_y=%d\n",lv_obj_get_x(btn),lv_obj_get_y(btn));
printf("btn_x=%d,btn_y=%d\n",lv_obj_get_width(btn),lv_obj_get_height(btn));
The coordinates of the print button before and after screen rotation are the same, and they are the first entity button used.How many coordinates should I set in points_array
Screenshot and/or video
If possible, add screenshots and/or videos about the current state.

Can give me some advice? Thank in advance
