Mouse pointer in frame buffer

Hello,

Is it possible to see mouse pointer when run LVGL application in frame buffer? How to achieve that? Currently I can click buttons with touchscreen, but I would like to play with mouse.

Of course! You just need to use the same code as the PC simulator:

github.com

lvgl/lv_sim_eclipse_sdl/blob/e164e3591c3e1e3bf3464d19e0dcdc67b2e6a791/main.c#L110-L114


/*Set a cursor for the mouse*/
LV_IMG_DECLARE(mouse_cursor_icon); /*Declare the image file.*/
lv_obj_t * cursor_obj = lv_img_create(lv_scr_act(), NULL); /*Create an image object for the cursor */
lv_img_set_src(cursor_obj, &mouse_cursor_icon);           /*Set the image source*/
lv_indev_set_cursor(mouse_indev, cursor_obj);             /*Connect the image  object to the driver*/

Here’s mouse_cursor_icon.c.
