So, we should add one (or more) of the following masks when we create our window: -* XCB_EVENT_MASK_KEY_PRESS: notify us when a key was pressed while any of our controlled windows had the keyboard focus. -* XCB_EVENT_MASK_KEY_RELEASE: notify us when a key was released while any of our controlled windows had the keyboard focus. + XCB_EVENT_MASK_KEY_PRESS // key was pressed while any of our controlled windows had the keyboard focus + XCB_EVENT_MASK_KEY_RELEASE // key was released while any of our controlled windows had the keyboard focus -The structure to be checked for in our events loop is the same for these two events, and is the following: - - typedef struct { - uint8_t response_type; /* The type of the event */ - xcb_keycode_t detail; - uint16_t sequence; - xcb_timestamp_t time; /* Time, in milliseconds the event took place in */ - xcb_window_t root; - xcb_window_t event; - xcb_window_t child; - int16_t root_x; - int16_t root_y; - int16_t event_x; - int16_t event_y; - uint16_t state; - uint8_t same_screen; - } xcb_key_press_event_t; +These generate events of the same type, which goes by two names: - typedef xcb_key_press_event_t xcb_key_release_event_t; + typedef struct { + uint8_t response_type; /* The type of the event */ + xcb_keycode_t detail; /* the physical key on the keyboard */ + uint16_t sequence; + xcb_timestamp_t time; /* Time, in milliseconds the event took place in */ + xcb_window_t root; + xcb_window_t event; + xcb_window_t child; + int16_t root_x; + int16_t root_y; + int16_t event_x; + int16_t event_y; + uint16_t state; + uint8_t same_screen; + } xcb_key_press_event_t; -The detail field refers to the physical key on the keyboard. + typedef xcb_key_press_event_t xcb_key_release_event_t; TODO: Talk about getting the ASCII code from the key code. |
