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);
26 * When the user moves the mouse pointer onto a window, this callback gets
30 int handle_enter_notify(void *ignored, xcb_connection_t *conn,
31 xcb_enter_notify_event_t *event);
34 * When the user moves the mouse but does not change the active window
35 * (e.g. when having no windows opened but moving mouse on the root screen
36 * and crossing virtual screen boundaries), this callback gets called.
39 int handle_motion_notify(void *ignored, xcb_connection_t *conn,
40 xcb_motion_notify_event_t *event);
43 * Called when the keyboard mapping changes (for example by using Xmodmap),
44 * we need to update our key bindings then (re-translate symbols).
47 int handle_mapping_notify(void *ignored, xcb_connection_t *conn,
48 xcb_mapping_notify_event_t *event);
51 * Checks if the button press was on a stack window, handles focus setting and
52 * returns true if so, or false otherwise.
55 int handle_button_press(void *ignored, xcb_connection_t *conn,
56 xcb_button_press_event_t *event);
59 * A new window appeared on the screen (=was mapped), so let’s manage it.
62 int handle_map_request(void *prophs, xcb_connection_t *conn,
63 xcb_map_request_event_t *event);
66 * Configuration notifies are only handled because we need to set up ignore
67 * for the following enter notify events
70 int handle_configure_event(void *prophs, xcb_connection_t *conn, xcb_configure_notify_event_t *event);
73 * Gets triggered upon a RandR screen change event, that is when the user
74 * changes the screen configuration in any way (mode, position, …)
77 int handle_screen_change(void *prophs, xcb_connection_t *conn,
78 xcb_generic_event_t *e);
81 * Configure requests are received when the application wants to resize
82 * windows on their own.
84 * We generate a synthethic configure notify event to signalize the client its
88 int handle_configure_request(void *prophs, xcb_connection_t *conn,
89 xcb_configure_request_event_t *event);
92 * Our window decorations were unmapped. That means, the window will be killed
93 * now, so we better clean up before.
96 int handle_unmap_notify_event(void *data, xcb_connection_t *conn, xcb_unmap_notify_event_t *event);
99 * A destroy notify event is sent when the window is not unmapped, but
100 * immediately destroyed (for example when starting a window and immediately
101 * killing the program which started it).
103 * We just pass on the event to the unmap notify handler (by copying the
104 * important fields in the event data structure).
107 int handle_destroy_notify_event(void *data, xcb_connection_t *conn,
108 xcb_destroy_notify_event_t *event);
111 * Called when a window changes its title

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

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

145 * Expose event means we should redraw our windows (= title bar)
148 int handle_expose_event(void *data, xcb_connection_t *conn,
149 xcb_expose_event_t *event);
152 * Handle client messages (EWMH)
155 int handle_client_message(void *data, xcb_connection_t *conn,
156 xcb_client_message_event_t *event);
159 * Handles _NET_WM_WINDOW_TYPE changes
162 int handle_window_type(void *data, xcb_connection_t *conn, uint8_t state,
163 xcb_window_t window, xcb_atom_t atom,
164 xcb_get_property_reply_t *property);
167 * Handles the size hints set by a window, but currently only the part
168 * necessary for displaying clients proportionally inside their frames
169 * (mplayer for example)
171 * See ICCCM 4.1.2.3 for more details
174 int handle_normal_hints(void *data, xcb_connection_t *conn, uint8_t state,
175 xcb_window_t window, xcb_atom_t name,
176 xcb_get_property_reply_t *reply);
179 * Handles the WM_HINTS property for extracting the urgency state of the window.
182 int handle_hints(void *data, xcb_connection_t *conn, uint8_t state, xcb_window_t window,
183 xcb_atom_t name, xcb_get_property_reply_t *reply);
186 * Handles the transient for hints set by a window, signalizing that this
187 * window is a popup window for some other window.
189 * See ICCCM 4.1.2.6 for more details
192 int handle_transient_for(void *data, xcb_connection_t *conn, uint8_t state,
193 xcb_window_t window, xcb_atom_t name,
194 xcb_get_property_reply_t *reply);
197 * Handles changes of the WM_CLIENT_LEADER atom which specifies if this is a
198 * toolwindow (or similar) and to which window it belongs (logical parent).
