Functions

void lv_x11_inputs_create(lv_display_t *disp, lv_image_dsc_t const *mouse_img)

create and add keyboard, mouse and scrillwheel objects and connect them to x11 display.

This is a convenience method handling the typical input initialisation of an X11 window:

  • create keyboard (lv_x11_keyboard_create)

  • create mouse (with scrollwheel, lv_x11_mouse_create lv_x11_mousewheel_create)

Parameters:

  • disp -- [in] the created X11 display object from lv_x11_window_create

  • mouse_img -- [in] optional image description for the mouse cursor (NULL for no/invisible mouse cursor)

lv_display_t *lv_x11_window_create(char const *title, int32_t hor_res, int32_t ver_res)

create the X11 display

The minimal initialisation for initializing the X11 display driver with keyboard/mouse support: 

lv_display_t* disp = lv_x11_window_create("My Window Title", window_width, window_width);
lv_x11_inputs_create(disp, NULL);
or with mouse cursor icon: 
lv_image_dsc_t mouse_symbol = {.....};
lv_display_t* disp = lv_x11_window_create("My Window Title", window_width, window_width);
lv_x11_inputs_create(disp, &mouse_symbol);

Parameters:

  • title -- [in] title of the created X11 window

  • hor_res -- [in] horizontal resolution (=width) of the X11 window

  • ver_res -- [in] vertical resolution (=height) of the X11 window

Returns:
