39 * There was a key press. We compare this key code with our bindings table and
40 * pass the bound action to parse_command().

47 * When the user moves the mouse pointer onto a window, this callback gets
51 int handle_enter_notify(void *ignored, xcb_connection_t *conn,
52 xcb_enter_notify_event_t *event);
55 * When the user moves the mouse but does not change the active window
56 * (e.g. when having no windows opened but moving mouse on the root screen
57 * and crossing virtual screen boundaries), this callback gets called.
60 int handle_motion_notify(void *ignored, xcb_connection_t *conn,
61 xcb_motion_notify_event_t *event);
64 * Called when the keyboard mapping changes (for example by using Xmodmap),
65 * we need to update our key bindings then (re-translate symbols).
68 int handle_mapping_notify(void *ignored, xcb_connection_t *conn,

72 * Checks if the button press was on a stack window, handles focus setting and
73 * returns true if so, or false otherwise.

80 * A new window appeared on the screen (=was mapped), so let’s manage it.

87 * Configuration notifies are only handled because we need to set up ignore

102 * Configure requests are received when the application wants to resize
103 * windows on their own.
105 * We generate a synthethic configure notify event to signalize the client its

113 * Our window decorations were unmapped. That means, the window will be killed
114 * now, so we better clean up before.
117 int handle_unmap_notify_event(void *data, xcb_connection_t *conn, xcb_unmap_notify_event_t *event);
120 * A destroy notify event is sent when the window is not unmapped, but
121 * immediately destroyed (for example when starting a window and immediately
122 * killing the program which started it).
124 * We just pass on the event to the unmap notify handler (by copying the
125 * important fields in the event data structure).

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