17 * Due to bindings like Mode_switch + <a>, we need to bind some keys in
18 * XCB_GRAB_MODE_SYNC. Therefore, we just replay all key presses.
21 int handle_key_release(void *ignored, xcb_connection_t *conn,
22 xcb_key_release_event_t *event);
25 * There was a key press. We compare this key code with our bindings table and
26 * pass the bound action to parse_command().
29 int handle_key_press(void *ignored, xcb_connection_t *conn,
30 xcb_key_press_event_t *event);
33 * When the user moves the mouse pointer onto a window, this callback gets
37 int handle_enter_notify(void *ignored, xcb_connection_t *conn,
38 xcb_enter_notify_event_t *event);
41 * When the user moves the mouse but does not change the active window
42 * (e.g. when having no windows opened but moving mouse on the root screen
43 * and crossing virtual screen boundaries), this callback gets called.
46 int handle_motion_notify(void *ignored, xcb_connection_t *conn,
47 xcb_motion_notify_event_t *event);
50 * Called when the keyboard mapping changes (for example by using Xmodmap),
51 * we need to update our key bindings then (re-translate symbols).
54 int handle_mapping_notify(void *ignored, xcb_connection_t *conn,
55 xcb_mapping_notify_event_t *event);
58 * Checks if the button press was on a stack window, handles focus setting and
59 * returns true if so, or false otherwise.
62 int handle_button_press(void *ignored, xcb_connection_t *conn,
63 xcb_button_press_event_t *event);
66 * A new window appeared on the screen (=was mapped), so let’s manage it.
69 int handle_map_request(void *prophs, xcb_connection_t *conn,
70 xcb_map_request_event_t *event);
73 * Configuration notifies are only handled because we need to set up ignore
74 * for the following enter notify events
77 int handle_configure_event(void *prophs, xcb_connection_t *conn, xcb_configure_notify_event_t *event);
80 * Gets triggered upon a RandR screen change event, that is when the user
81 * changes the screen configuration in any way (mode, position, …)
84 int handle_screen_change(void *prophs, xcb_connection_t *conn,
85 xcb_generic_event_t *e);
88 * Configure requests are received when the application wants to resize
89 * windows on their own.
91 * We generate a synthethic configure notify event to signalize the client its
95 int handle_configure_request(void *prophs, xcb_connection_t *conn,
96 xcb_configure_request_event_t *event);
99 * Our window decorations were unmapped. That means, the window will be killed
100 * now, so we better clean up before.
103 int handle_unmap_notify_event(void *data, xcb_connection_t *conn, xcb_unmap_notify_event_t *event);
106 * Called when a window changes its title

110 xcb_window_t window, xcb_atom_t atom,

114 * We handle legacy window names (titles) which are in COMPOUND_TEXT
115 * encoding. However, we just pass them along, so when containing non-ASCII
116 * characters, those will be rendering incorrectly. In order to correctly
117 * render unicode window titles in i3, an application has to set _NET_WM_NAME,
118 * which is in UTF-8 encoding.
120 * On every update, a message is put out to the user, so he may improve the
121 * situation and update applications which display filenames in their title to
122 * correctly use _NET_WM_NAME and therefore support unicode.

140 * Expose event means we should redraw our windows (= title bar)
143 int handle_expose_event(void *data, xcb_connection_t *conn,
144 xcb_expose_event_t *event);
147 * Handle client messages (EWMH)
150 int handle_client_message(void *data, xcb_connection_t *conn,
151 xcb_client_message_event_t *event);
154 * Handles _NET_WM_WINDOW_TYPE changes

158 xcb_window_t window, xcb_atom_t atom,

162 * Handles the size hints set by a window, but currently only the part
163 * necessary for displaying clients proportionally inside their frames
164 * (mplayer for example)
166 * See ICCCM 4.1.2.3 for more details
169 int handle_normal_hints(void *data, xcb_connection_t *conn, uint8_t state,
170 xcb_window_t window, xcb_atom_t name,

174 * Handles the WM_HINTS property for extracting the urgency state of the window.
177 int handle_hints(void *data, xcb_connection_t *conn, uint8_t state, xcb_window_t window,
178 xcb_atom_t name, xcb_get_property_reply_t *reply);
181 * Handles the transient for hints set by a window, signalizing that this
182 * window is a popup window for some other window.
184 * See ICCCM 4.1.2.6 for more details

192 * Handles changes of the WM_CLIENT_LEADER atom which specifies if this is a
193 * toolwindow (or similar) and to which window it belongs (logical parent).
