## Detailed Description

The window class of Elementary. Contains functions to manipulate windows. The Evas engine used to render the window contents is specified in the system or user elementary config files (whichever is found last), and can be overridden with the ELM_ENGINE environment variable for testing. Engines that may be supported (depending on Evas and Ecore-Evas compilation setup and modules actually installed at runtime) are (listed in order of best supported and most likely to be complete and work to lowest quality). Note that ELM_ENGINE is really only needed for special cases and debugging. you should normally use ELM_DISPLAY and ELM_ACCEL environment variables, or core elementary config. ELM_DISPLAY can be set to "x11" or "wl" to indicate the target display system (as on Linux systems you may have both display systems available, so this selects which to use). ELM_ACCEL may also be set to indicate if you want accelerations and which kind to use. see elm_config_accel_preference_set(0 for details on this environment variable values.

- "x11", "x", "software-x11", "software_x11" (Software rendering in X11)
- "gl", "opengl", "opengl-x11", "opengl_x11" (OpenGL or OpenGL-ES2 rendering in X11)
- "shot:..." (Virtual screenshot renderer - renders to output file and exits)
- "fb", "software-fb", "software_fb" (Linux framebuffer direct software rendering)
- "sdl", "software-sdl", "software_sdl" (SDL software rendering to SDL buffer)
- "gl-sdl", "gl_sdl", "opengl-sdl", "opengl_sdl" (OpenGL or OpenGL-ES2 rendering using SDL as the buffer)
- "gdi", "software-gdi", "software_gdi" (Windows WIN32 rendering via GDI with software)
- "ddraw", "software-ddraw", "software_ddraw" (Windows WIN32 rendering via DirectDraw with software)
- "gl-cocoa", "gl_cocoa", "opengl-cocoa", "opengl_cocoa" (OpenGL rendering in Cocoa)
- "wayland_shm" (Wayland client SHM rendering)
- "wayland_egl" (Wayland client OpenGL/EGL rendering)
- "drm" (Linux drm/kms etc. direct display)

All engines use a simple string to select the engine to render, EXCEPT the "shot" engine. This actually encodes the output of the virtual screenshot and how long to delay in the engine string. The engine string is encoded in the following way:

"shot:[delay=XX][:][repeat=DDD][:][file=XX]"

Where options are separated by a ":" char if more than one option is given, with delay, if provided being the first option and file the last (order is important). The delay specifies how long to wait after the window is shown before doing the virtual "in memory" rendering and then save the output to the file specified by the file option (and then exit). If no delay is given, the default is 0.5 seconds. If no file is given the default output file is "out.png". Repeat option is for continuous capturing screenshots. Repeat range is from 1 to 999 and filename is fixed to "out001.png" Some examples of using the shot engine:

ELM_ENGINE="shot:delay=1.0:repeat=5:file=elm_test.png" elementary_test ELM_ENGINE="shot:delay=1.0:file=elm_test.png" elementary_test ELM_ENGINE="shot:file=elm_test2.png" elementary_test ELM_ENGINE="shot:delay=2.0" elementary_test ELM_ENGINE="shot:" elementary_test

Signals that you can add callbacks for are:

- "delete,request": the user requested to close the window. See elm_win_autodel_set() and elm_win_autohide_set().
- "focus,in": window got focus (deprecated. use "focused" instead.)
- "focus,out": window lost focus (deprecated. use "unfocused" instead.)
- "moved": window that holds the canvas was moved
- "withdrawn": window is still managed normally but removed from view
- "iconified": window is minimized (perhaps into an icon or taskbar)
- "normal": window is in a normal state (not withdrawn or iconified)
- "stick": window has become sticky (shows on all desktops)
- "unstick": window has stopped being sticky
- "fullscreen": window has become fullscreen
- "unfullscreen": window has stopped being fullscreen
- "maximized": window has been maximized
- "unmaximized": window has stopped being maximized
- "ioerr": there has been a low-level I/O error with the display system
- "indicator,prop,changed": an indicator's property has been changed
- "rotation,changed": window rotation has been changed
- "profile,changed": profile of the window has been changed
- "focused" : When the win has received focus. (since 1.8)
- "unfocused" : When the win has lost focus. (since 1.8)
- "theme,changed" - The theme was changed. (since 1.13)

Note that calling evas_object_show() after window contents creation is recommended. It will trigger evas_smart_objects_calculate() and some backend calls directly. For example, XMapWindow is called directly during evas_object_show() in X11 engine.

## Typedef Documentation

## ◆ Elm_Win_Trap

Elm_Win_Trap

Trap can be set with elm_win_trap_set() and will intercept the calls to internal ecore_evas with the same name and parameters.

If there is a trap and it returns `EINA_TRUE` then the call will be allowed, otherwise it will be ignored.

Since
  1.7

## Enumeration Type Documentation

## ◆ Elm_Win_Indicator_Mode

enum Elm_Win_Indicator_Mode

In some environments, like phones, you may have an indicator that shows battery status, reception, time etc.

This is the indicator.

Sometimes you don't want it because you provide the same functionality inside your app, so this will request that the indicator is hidden in this circumstance. The default is depend on the environments. For example, like phones, default is to have the indicator shown. But like TV, default is to have the indicator hidden.

Enumerator
ELM_WIN_INDICATOR_HIDE | Unknown indicator state.
ELM_WIN_INDICATOR_SHOW | Hides the indicator. Shows the indicator

## ◆ Elm_Win_Indicator_Opacity_Mode

enum Elm_Win_Indicator_Opacity_Mode

Defines the opacity modes of indicator that can be shown.

Enumerator
ELM_WIN_INDICATOR_OPAQUE | Unknown indicator opacity mode.
ELM_WIN_INDICATOR_TRANSLUCENT | Opacifies the indicator.
ELM_WIN_INDICATOR_TRANSPARENT | Be translucent the indicator. Transparentizes the indicator

## ◆ Elm_Win_Type

enum Elm_Win_Type

Defines the types of window that can be created.

These are hints set on a window so that a running Window Manager knows how the window should be handled and/or what kind of decorations it should have.

Currently, only the X11 backed engines use them.

Enumerator
ELM_WIN_UNKNOWN | Default, unknown, type.
ELM_WIN_BASIC | A normal window. Indicates a normal, top-level window. Almost every window will be created with this type.
ELM_WIN_DIALOG_BASIC | Used for simple dialog windows.
ELM_WIN_DESKTOP | For special desktop windows, like a background window holding desktop icons.
ELM_WIN_DOCK | The window is used as a dock or panel. Usually would be kept on top of any other window by the Window Manager.
ELM_WIN_TOOLBAR | The window is used to hold a floating toolbar, or similar.
ELM_WIN_MENU | Similar to .toolbar.
ELM_WIN_UTILITY | A persistent utility window, like a toolbox or palette.
ELM_WIN_SPLASH | Splash window for a starting up application.
ELM_WIN_DROPDOWN_MENU | The window is a dropdown menu, as when an entry in a menubar is clicked. This hint exists for completion only, as the EFL way of implementing a menu would not normally use a separate window for its contents.
ELM_WIN_POPUP_MENU | Like .dropdown_menu, but for the menu triggered by right-clicking an object.
ELM_WIN_TOOLTIP | The window is a tooltip. A short piece of explanatory text that typically appear after the mouse cursor hovers over an object for a while. Typically not very commonly used in the EFL.
ELM_WIN_NOTIFICATION | A notification window, like a warning about battery life or a new E-Mail received.
ELM_WIN_COMBO | A window holding the contents of a combo box. Not usually used in the EFL.
ELM_WIN_DND | Used to indicate the window is a representation of an object being dragged across different windows, or even applications. Typically used with elm_win_override_set().
ELM_WIN_INLINED_IMAGE | The window is an image.
ELM_WIN_SOCKET_IMAGE | The window is an image received through a socket.
ELM_WIN_FAKE | See elm_win_fake_add(). Since 1.13
ELM_WIN_NAVIFRAME_BASIC | Used for naviframe style replacement with a back button instead of a close button. Since 1.19

## ◆ elm_win_autodel_set()

void elm_win_autodel_set | ( | Evas_Object * | obj,
|  | Eina_Bool | autodel
| ) |  |

Set the window's autodel state.

When closing the window in any way outside of the program control, like pressing the X button in the titlebar or using a command from the Window Manager, a "delete,request" signal is emitted to indicate that this event occurred and the developer can take any action, which may include, or not, destroying the window object.

When the `autodel` parameter is set, the window will be automatically destroyed when this event occurs, after the signal is emitted. If `autodel` is `false`, then the window will not be destroyed and is up to the program to do so when it's required.

Parameters

  [in] | obj | The object.
  [in] | autodel | If `true`, the window will automatically delete itself when closed.

## ◆ elm_win_add()

Evas_Object * elm_win_add | ( | Evas_Object * | parent,

|  | Elm_Win_Type | type
| ) |  |

Adds a window object.

If this is the first window created, pass NULL as `parent`.

Parameters

  parent | Parent object to add the window to, or NULL
  name | The name of the window
  type | The window type, one of Elm_Win_Type.

The `parent` parameter can be `NULL` for every window `type` except ELM_WIN_INLINED_IMAGE, which needs a parent to retrieve the canvas on which the image object will be created.

Returns
  The created object, or `NULL` on failure

| ) |  |

Set the floating mode of a window.

Parameters

  obj | The window object
  floating | If true, the window is floating mode

The floating mode can be used on mobile environment. For example, if the video-player window sets the floating mode, then e (enlightenment window manager) changes its geometry and handles it like a popup. This is similar to a multi window concept in a mobile phone. The way of handling floating mode window is decided by enlightenment window manager.

## ◆ elm_win_norender_push()

void elm_win_norender_push | ( | Evas_Object * | obj | ) |

This pushes (increments) the norender counter on the window.

Parameters

  obj | The window object

There are some occasions where you wish to suspend rendering on a window. You may be "sleeping" and have nothing to update and do not want animations or other theme side-effects causing rendering to the window while "asleep". You can push (and pop) the norender mode to have this work.

If combined with evas_render_dump(), evas_image_cache_flush() and evas_font_cache_flush() (and maybe edje_file_cache_flush() and edje_collection_cache_flush()), you can minimize memory footprint significantly while "asleep", and the pausing of rendering ensures evas does not re-load data into memory until needed. When rendering is resumed, data will be re-loaded as needed, which may result in some lag, but does save memory.

## ◆ elm_win_norender_pop()

void elm_win_norender_pop | ( | Evas_Object * | obj | ) |

This pops (decrements) the norender counter on the window.

Parameters

  obj | The window object

Once norender has gone back to 0, then automatic rendering will continue in the given window. If it is already at 0, this will have no effect.

## ◆ elm_win_render()

void elm_win_render | ( | Evas_Object * | obj | ) |

This manually asks evas to render the window now.

Parameters

  obj | The window object

You should NEVER call this unless you really know what you are doing and why. Never call this unless you are asking for performance degradation and possibly weird behavior. Windows get automatically rendered when the application goes into the idle enter state so there is never a need to call this UNLESS you have enabled "norender" mode.

## ◆ elm_win_resize_object_add()

void elm_win_resize_object_add | ( | Evas_Object * | obj,
|  | Evas_Object * | subobj
| ) |  |

Add `subobj` as a resize object of window `obj`.

Setting an object as a resize object of the window means that the `subobj` child's size and position will be controlled by the window directly. That is, the object will be resized to match the window size and should never be moved or resized manually by the developer.

In addition, resize objects of the window control what the minimum size of it will be, as well as whether it can or not be resized by the user.

For the end user to be able to resize a window by dragging the handles or borders provided by the Window Manager, or using any other similar mechanism, all of the resize objects in the window should have their evas_object_size_hint_weight_set set to EVAS_HINT_EXPAND.

Also notice that the window can get resized to the current size of the object if the EVAS_HINT_EXPAND is set after the call to this. So if the object should get resized to the size of the window, set this hint before adding it as a resize object (this happens because the size of the window and the object are evaluated as soon as the object is added to the window).

Parameters

  [in] | subobj | The resize object to add.

This function removes the object `subobj` from the resize objects of the window `obj`. It will not delete the object itself, which will be left unmanaged and should be deleted by the developer, manually handled or set as child of some other container.

Parameters

  [in] | subobj | The resize object to add.

## ◆ elm_win_accel_preference_get()

const char * elm_win_accel_preference_get | ( | const Evas_Object * | obj | ) |

The hardware acceleration preference for this window.

This is a constructor function and can only be called before Efl.Object.finalize.

This property overrides the global EFL configuration option "accel_preference" for this single window, and accepts the same syntax.

The `accel` string is a freeform C string that indicates what kind of acceleration is preferred. Here "acceleration" generally refers to rendering and the hardware with which the unit application renders GUIs. This may or may not be honored but a best attempt will be made. Known strings are as follows:

"gl", "opengl" - try use OpenGL. "3d" - try to use a 3d acceleration unit. "hw", "hardware", "accel" - try any acceleration unit (best possible) "none"

- use no acceleration but software instead (since 1.16)

Since 1.14, it is also possible to specify some GL properties for the GL window surface. This allows applications to use GLView with depth, stencil and MSAA buffers with direct rendering. The new accel preference string format is thus "{HW Accel}[:depth{value}[:stencil{value}[:msaa{str}$]$]$]".

Accepted values for depth are for instance "depth", "depth16", "depth24". Accepted values for stencil are "stencil", "stencil1", "stencil8". For MSAA, only predefined strings are accepted: "msaa", "msaa_low", "msaa_mid" and "msaa_high". The selected configuration is not guaranteed and is only valid in case of GL acceleration. Only the base acceleration string will be saved (e.g. "gl" or "hw").

Full examples include:

"gl", - try to use OpenGL "hw:depth:stencil", - use HW acceleration with default depth and stencil buffers "opengl:depth24:stencil8:msaa_mid" - use OpenGL with 24-bit depth, 8-bit stencil and a medium number of MSAA samples in the backbuffer.

Note that this option may be overriden by environment variables or the configuration option "accel_preference_override".

This will return the value of "accel_preference" when the window was created.

Parameters

  [in] | obj | The object.

Returns
  Acceleration

Since
  1.18

## ◆ elm_win_alpha_set()

void elm_win_alpha_set | ( | Evas_Object * | obj,
|  | Eina_Bool | alpha
| ) |  |

Activate a window object.

This function sends a request to the Window Manager to activate the window pointed by `obj`. If honored by the WM, the window will receive the keyboard focus.

Note
  This is just a request that a Window Manager may ignore, so calling this function does not ensure in any way that the window will be the active one afterwards.

Parameters

  [in] | obj | The object.

## ◆ elm_win_center()

void elm_win_center | ( | Evas_Object * | obj,
|  | Eina_Bool | h,

| ) |  |

Center a window on the screen.

This function centers window `obj` horizontally and/or vertically based on the values of `h` and `v`.

Note
  This is just a request that a Window Manager may ignore, so calling this function does not ensure in any way that the window will be centered afterwards.

Parameters

  [in] | obj | The object.
  [in] | h | If `true`, center horizontally. If `false`, do not change horizontal location.
  [in] | v | If `true`, center vertically. If `false`, do not change vertical location.

Start moving or resizing the window.

The user can request the display server to start moving or resizing the window by combining modes from Efl_Ui_Win_Move_Resize_Mode. This API can only be called if none of the following conditions is true:

1. Called in the absence of a pointer down event, 2. Called more than once before a pointer up event, 3. Called when the window is already being resized or moved, 4. Called with an unsupported combination of modes.

Right usage: 1. Pointer (mouse or touch) down event, 2. elm_win_move_resize_start called only once with a supported mode, 3. Pointer (mouse or touch) up event.

If a pointer up event occurs after calling the function, it automatically ends the window move and resize operation.

Currently, only the following 9 combinations are allowed, and possibly more combinations may be added in the future: 1. ELM_WIN_MOVE_RESIZE_MOVE

1. ELM_WIN_MOVE_RESIZE_TOP 3. ELM_WIN_MOVE_RESIZE_BOTTOM 4. ELM_WIN_MOVE_RESIZE_LEFT 5. ELM_WIN_MOVE_RESIZE_RIGHT 6. ELM_WIN_MOVE_RESIZE_TOP | ELM_WIN_MOVE_RESIZE_LEFT 7. ELM_WIN_MOVE_RESIZE_TOP | ELM_WIN_MOVE_RESIZE_RIGHT 8. ELM_WIN_MOVE_RESIZE_BOTTOM | ELM_WIN_MOVE_RESIZE_LEFT 9. ELM_WIN_MOVE_RESIZE_BOTTOM | ELM_WIN_MOVE_RESIZE_RIGHT

In particular move and resize cannot happen simultaneously.

Note
  the result of this API can only guarantee that the request has been forwarded to the server, but there is no guarantee that the request can be processed by the display server.

Parameters

  [in] | obj | The object.
  [in] | mode | The requested move or resize mode.

Returns
  `true` if the request was successfully sent to the display server, `false` in case of error.
