17 * There was a key press. We compare this key code with our bindings table and
18 * pass the bound action to parse_command().
21 int handle_key_press(void *ignored, xcb_connection_t *conn,
22 xcb_key_press_event_t *event);
25 * When the user moves the mouse pointer onto a window, this callback gets
29 int handle_enter_notify(void *ignored, xcb_connection_t *conn,
30 xcb_enter_notify_event_t *event);
33 * When the user moves the mouse but does not change the active window
34 * (e.g. when having no windows opened but moving mouse on the root screen
35 * and crossing virtual screen boundaries), this callback gets called.
38 int handle_motion_notify(void *ignored, xcb_connection_t *conn,
39 xcb_motion_notify_event_t *event);
42 * Called when the keyboard mapping changes (for example by using Xmodmap),
43 * we need to update our key bindings then (re-translate symbols).
46 int handle_mapping_notify(void *ignored, xcb_connection_t *conn,
47 xcb_mapping_notify_event_t *event);
50 * Checks if the button press was on a stack window, handles focus setting and
51 * returns true if so, or false otherwise.
54 int handle_button_press(void *ignored, xcb_connection_t *conn,
55 xcb_button_press_event_t *event);
58 * A new window appeared on the screen (=was mapped), so let’s manage it.
61 int handle_map_request(void *prophs, xcb_connection_t *conn,
62 xcb_map_request_event_t *event);
65 * Configuration notifies are only handled because we need to set up ignore
66 * for the following enter notify events
69 int handle_configure_event(void *prophs, xcb_connection_t *conn, xcb_configure_notify_event_t *event);
72 * Gets triggered upon a RandR screen change event, that is when the user
73 * changes the screen configuration in any way (mode, position, …)
76 int handle_screen_change(void *prophs, xcb_connection_t *conn,
77 xcb_generic_event_t *e);
80 * Configure requests are received when the application wants to resize
81 * windows on their own.
83 * We generate a synthethic configure notify event to signalize the client its
87 int handle_configure_request(void *prophs, xcb_connection_t *conn,
88 xcb_configure_request_event_t *event);
91 * Our window decorations were unmapped. That means, the window will be killed
92 * now, so we better clean up before.
95 int handle_unmap_notify_event(void *data, xcb_connection_t *conn, xcb_unmap_notify_event_t *event);
98 * A destroy notify event is sent when the window is not unmapped, but
99 * immediately destroyed (for example when starting a window and immediately
100 * killing the program which started it).
102 * We just pass on the event to the unmap notify handler (by copying the
103 * important fields in the event data structure).
106 int handle_destroy_notify_event(void *data, xcb_connection_t *conn,
107 xcb_destroy_notify_event_t *event);
110 * Called when a window changes its title

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

135 * Store the window classes for jumping to them later.

144 * Expose event means we should redraw our windows (= title bar)
147 int handle_expose_event(void *data, xcb_connection_t *conn,
148 xcb_expose_event_t *event);
151 * Handle client messages (EWMH)
154 int handle_client_message(void *data, xcb_connection_t *conn,
155 xcb_client_message_event_t *event);
158 * Handles _NET_WM_WINDOW_TYPE changes
161 int handle_window_type(void *data, xcb_connection_t *conn, uint8_t state,
162 xcb_window_t window, xcb_atom_t atom,
163 xcb_get_property_reply_t *property);
166 * Handles the size hints set by a window, but currently only the part
167 * necessary for displaying clients proportionally inside their frames
168 * (mplayer for example)
170 * See ICCCM 4.1.2.3 for more details
173 int handle_normal_hints(void *data, xcb_connection_t *conn, uint8_t state,
174 xcb_window_t window, xcb_atom_t name,
175 xcb_get_property_reply_t *reply);
178 * Handles the WM_HINTS property for extracting the urgency state of the window.
181 int handle_hints(void *data, xcb_connection_t *conn, uint8_t state, xcb_window_t window,
182 xcb_atom_t name, xcb_get_property_reply_t *reply);
185 * Handles the transient for hints set by a window, signalizing that this
186 * window is a popup window for some other window.
188 * See ICCCM 4.1.2.6 for more details
191 int handle_transient_for(void *data, xcb_connection_t *conn, uint8_t state,
192 xcb_window_t window, xcb_atom_t name,
193 xcb_get_property_reply_t *reply);
196 * Handles changes of the WM_CLIENT_LEADER atom which specifies if this is a
197 * toolwindow (or similar) and to which window it belongs (logical parent).
