Fields

start: Option<unsafe extern "C" fn(obj: *mut conf_object_t, backend: *mut conf_object_t) -> c_int>

Called when the backend is finalised. Should return a unique handle identifying the given backend object to the frontend.

stop: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int)>

Called when the backend is being destroyed.

set_title: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, short_title: *const c_char, long_title: *const c_char)>

Set window title of the frontend associated to the specified backend. Two title strings are given, where the long title is meant for a window title bar and the short for a window list. The long title string is at least as long as the short.

set_size: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, width: c_int, height: c_int)>

Called when the screen size of the specified backend changes.

set_visible: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, visible: bool)>

Tell the frontend to show/hide its GUI window.

set_contents: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, left: c_int, top: c_int, right: c_int, bottom: c_int, data: *const uint32)>

Update the screen contents in the rectangle between (left, top) and (right, bottom), inclusive. ‘data’ is the start of the screen pixel array, so the first pixel of the rectangle is at &data[width * top + left], where width was set by set_size.

invalidate_contents: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int)>

Tell the frontend that the data argument passed to set_contents is no longer valid. This must be called upon a screen size change, before set_size.

set_text_mode: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, text_mode: bool)>

Inform the frontend whether or not we are currently in VGA text mode.

signal_text_update: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int)>

Tell the frontend that text arrived to the backend from the attached device, using vga_text_update.

set_grab_mode: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, active: bool)>

Inform the frontend that the grab mode of the specified backend has changed.

set_mouse_pos: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, x: c_int, y: c_int)>

Tell the frontend to set the host mouse cursor to (x, y), with ranges [0, width - 1] and [0, height - 1], where width and height were set by set_size.

set_keyboard_leds: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, led_state: gfx_console_led_t)>

Inform frontend that the keyboard LED state have been updated. The new state of the LEDs is given as a bitmask.

set_grab_modifier: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, modifier: sim_key_t)>

Inform frontend that the grab modifier has changed.

set_grab_button: Option<unsafe extern "C" fn(obj: *mut conf_object_t, handle: c_int, button: gfx_console_mouse_button_t)>

Inform frontend that the grab button has changed.
