15 * Due to bindings like Mode_switch + <a>, we need to bind some keys in
16 * XCB_GRAB_MODE_SYNC. Therefore, we just replay all key presses.
19 int handle_key_release(void *ignored, xcb_connection_t *conn,
20 xcb_key_release_event_t *event);
23 * There was a key press. We compare this key code with our bindings table and
24 * pass the bound action to parse_command().
27 int handle_key_press(void *ignored, xcb_connection_t *conn,
28 xcb_key_press_event_t *event);
31 * When the user moves the mouse pointer onto a window, this callback gets
35 int handle_enter_notify(void *ignored, xcb_connection_t *conn,
36 xcb_enter_notify_event_t *event);
39 * When the user moves the mouse but does not change the active window
40 * (e.g. when having no windows opened but moving mouse on the root screen
41 * and crossing virtual screen boundaries), this callback gets called.
44 int handle_motion_notify(void *ignored, xcb_connection_t *conn,
45 xcb_motion_notify_event_t *event);
48 * Checks if the button press was on a stack window, handles focus setting and
49 * returns true if so, or false otherwise.
52 int handle_button_press(void *ignored, xcb_connection_t *conn,
53 xcb_button_press_event_t *event);
56 * A new window appeared on the screen (=was mapped), so let’s manage it.
59 int handle_map_request(void *prophs, xcb_connection_t *conn,
60 xcb_map_request_event_t *event);
63 * Configuration notifies are only handled because we need to set up ignore
64 * for the following enter notify events
67 int handle_configure_event(void *prophs, xcb_connection_t *conn, xcb_configure_notify_event_t *event);
70 * Configure requests are received when the application wants to resize
71 * windows on their own.
73 * We generate a synthethic configure notify event to signalize the client its
77 int handle_configure_request(void *prophs, xcb_connection_t *conn,
78 xcb_configure_request_event_t *event);
81 * Our window decorations were unmapped. That means, the window will be killed
82 * now, so we better clean up before.
85 int handle_unmap_notify_event(void *data, xcb_connection_t *conn, xcb_unmap_notify_event_t *event);
88 * Called when a window changes its title

92 xcb_window_t window, xcb_atom_t atom,
93 xcb_get_property_reply_t *prop);
96 * We handle legacy window names (titles) which are in COMPOUND_TEXT
97 * encoding. However, we just pass them along, so when containing non-ASCII
98 * characters, those will be rendering incorrectly. In order to correctly
99 * render unicode window titles in i3, an application has to set _NET_WM_NAME,
100 * which is in UTF-8 encoding.
102 * On every update, a message is put out to the user, so he may improve the
103 * situation and update applications which display filenames in their title to
104 * correctly use _NET_WM_NAME and therefore support unicode.

122 * Expose event means we should redraw our windows (= title bar)
125 int handle_expose_event(void *data, xcb_connection_t *conn,
126 xcb_expose_event_t *event);
129 * Handle client messages (EWMH)
132 int handle_client_message(void *data, xcb_connection_t *conn,

136 * Handles _NET_WM_WINDOW_TYPE changes

140 xcb_window_t window, xcb_atom_t atom,

144 * Handles the size hints set by a window, but currently only the part
145 * necessary for displaying clients proportionally inside their frames
146 * (mplayer for example)
148 * See ICCCM 4.1.2.3 for more details

152 xcb_window_t window, xcb_atom_t name,
153 xcb_get_property_reply_t *reply);
156 * Handles the transient for hints set by a window, signalizing that this
157 * window is a popup window for some other window.
159 * See ICCCM 4.1.2.6 for more details
162 int handle_transient_for(void *data, xcb_connection_t *conn, uint8_t state,
163 xcb_window_t window, xcb_atom_t name,
164 xcb_get_property_reply_t *reply);
167 * Handles changes of the WM_CLIENT_LEADER atom which specifies if this is a
168 * toolwindow (or similar) and to which window it belongs (logical parent).
