Detailed Description

Field Documentation

event_type

int ui_event_base_s::event_type

The type of event (0x10 being key event)

See also

ui_event_type_e List of event types.

key_code0

unsigned short ui_event_base_s::key_code0

Keycode for the first pressed key.

Only available when event_type is UI_EVENT_TYPE_KEY.

key_code1

unsigned short ui_event_base_s::key_code1

Keycode for the second pressed key.

Only available when event_type is UI_EVENT_TYPE_KEY.

Note

Depending on the exact keys pressed simultaneously, this is not always accurate. Moreover, some devices may lack support of simultaneous key presses.

recipient

ui_component_t* ui_event_base_s::recipient

Event recipient.

If set to NULL, the event is a broadcast event (e.g. input event). Otherwise, the widget's ui_component_t::on_event callback will be called with this event.

scroll_wheel

unsigned int ui_event_base_s::scroll_wheel

Scroll wheel direction, either SCROLL_DOWN or SCROLL_UP.

See also

scroll_wheel_e

touch_x

unsigned short ui_event_base_s::touch_x

The X coordinate of where the touch event is located, in pixels.

Only available when event_type is UI_EVENT_TYPE_TOUCH_BEGIN, UI_EVENT_TYPE_TOUCH_MOVE, or UI_EVENT_TYPE_TOUCH_END.

touch_y

unsigned short ui_event_base_s::touch_y

The Y coordinate of where the touch event is located, in pixels.

Only available when event_type is UI_EVENT_TYPE_TOUCH_BEGIN, UI_EVENT_TYPE_TOUCH_MOVE, or UI_EVENT_TYPE_TOUCH_END.

unk16

void* ui_event_base_s::unk16

Unknown.

Maybe used on event types other than touch and key press.

unk20

void* ui_event_base_s::unk20

Unknown.

Seems to be always 0, although ClearEvent() explicitly sets this to 0. Maybe used on event types other than touch and key press.

usb_data

void* ui_event_base_s::usb_data

Unknown.

Set along with a KEY_USB_INSERTION event. Seems to point to some data. Exact purpose unknown.
