11 * The window class of Elementary. Contains functions to manipulate
12 * windows. The Evas engine used to render the window contents is specified
13 * in the system or user elementary config files (whichever is found last),
14 * and can be overridden with the ELM_ENGINE environment variable for
15 * testing. Engines that may be supported (depending on Evas and Ecore-Evas
16 * compilation setup and modules actually installed at runtime) are (listed
17 * in order of best supported and most likely to be complete and work to
20 * @li "x11", "x", "software-x11", "software_x11" (Software rendering in X11)
21 * @li "gl", "opengl", "opengl-x11", "opengl_x11" (OpenGL or OpenGL-ES2

44 * @li "psl1ght" (PS3 rendering using PSL1GHT)
46 * All engines use a simple string to select the engine to render, EXCEPT
47 * the "shot" engine. This actually encodes the output of the virtual
48 * screenshot and how long to delay in the engine string. The engine string
49 * is encoded in the following way:
51 * "shot:[delay=XX][:][repeat=DDD][:][file=XX]"
53 * Where options are separated by a ":" char if more than one option is
54 * given, with delay, if provided being the first option and file the last
55 * (order is important). The delay specifies how long to wait after the
56 * window is shown before doing the virtual "in memory" rendering and then
57 * save the output to the file specified by the file option (and then exit).
58 * If no delay is given, the default is 0.5 seconds. If no file is given the
59 * default output file is "out.png". Repeat option is for continuous
60 * capturing screenshots. Repeat range is from 1 to 999 and filename is
61 * fixed to "out001.png" Some examples of using the shot engine:
63 * ELM_ENGINE="shot:delay=1.0:repeat=5:file=elm_test.png" elementary_test
64 * ELM_ENGINE="shot:delay=1.0:file=elm_test.png" elementary_test
65 * ELM_ENGINE="shot:file=elm_test2.png" elementary_test
66 * ELM_ENGINE="shot:delay=2.0" elementary_test
67 * ELM_ENGINE="shot:" elementary_test
69 * Signals that you can add callbacks for are:
71 * @li "delete,request": the user requested to close the window. See
72 * elm_win_autodel_set().
73 * @li "focus,in": window got focus
74 * @li "focus,out": window lost focus
75 * @li "moved": window that holds the canvas was moved
76 * @li "withdrawn": window is still managed normally but removed from view
77 * @li "iconified": window is minimized (perhaps into an icon or taskbar)
78 * @li "normal": window is in a normal state (not withdrawn or iconified)
79 * @li "stick": window has become sticky (shows on all desktops)
80 * @li "unstick": window has stopped being sticky
81 * @li "fullscreen": window has become fullscreen
82 * @li "unfullscreen": window has stopped being fullscreen
83 * @li "maximized": window has been maximized
84 * @li "unmaximized": window has stopped being maximized
85 * @li "ioerr": there has been a low-level I/O error with the display system
88 * @li @ref win_example_01

96 * how the window should be handled and/or what kind of decorations it
