Tizen Native API  5.5

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)
  • "ews" (rendering to EWS - Ecore + Evas Single Process Windowing System)
  • "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)
  • "conformant,changed" - conformant changed
  • "aux,hint,allowed" - an aux hint allowed
  • "aux,msg,received" - an aux message received
  • "effect,started" - window effect has been started.
  • "effect,done" - window effect has been done.
  • "launch,done" - window launch has been done.
  • "visibility,changed" - visibility of the window has been changed.

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.

Enumeration Type Documentation

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.

Function Documentation

void elm_win_activate ( Evas_Object obj)

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]objThe object.
Since :
2.3
Examples:
win_example.c.
Evas_Object* elm_win_add ( Evas_Object parent,
const char *  name,
Elm_Win_Type  type 
)

Adds a window object. If this is the first window created, pass NULL as parent.

Parameters:
parentParent object to add the window to, or NULL
nameThe name of the window
typeThe 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
Since :
2.3
Examples:
bg_example_02.c, and win_example.c.

Get the alpha channel state of a window.

Parameters:
[in]objThe object.

Examples:
win_example.c.
void elm_win_alpha_set ( Evas_Object obj,
Eina_Bool  alpha 
)

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]objThe object.
Returns:
Acceleration
Since (EFL) :
1.18 Set the alpha channel state of a window.

If alpha is true, the alpha channel of the canvas will be enabled possibly making parts of the window completely or partially transparent. This is also subject to the underlying system supporting it, for example a system using a compositing manager.

Note:
Alpha window can be enabled automatically by window theme style's property. If "alpha" data.item is "1" or "true" in window style(eg. elm/win/base/default), the window is switched to alpha automatically without the explicit api call.
Parameters:
[in]objThe object.
[in]alphatrue if the window alpha channel is enabled, false otherwise.

Since :
2.3

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]objThe object.
[in]autodelIf true, the window will automatically delete itself when closed.

Window's autohide 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 this property is set to true, the window will be automatically hidden when this event occurs, after the signal is emitted. If this property is false nothing will happen, beyond the event emission.

C applications can use this option along with the quit policy ELM_POLICY_QUIT_LAST_WINDOW_HIDDEN which allows exiting EFL's main loop when all the windows are hidden.

Note:
autodel and autohide are not mutually exclusive. The window will be deleted if both are set to true.
Parameters:
[in]objThe object.
Returns:
If true, the window will automatically hide itself when closed.

The window auxiliary hint is the value that is used to decide which action should be made available to the user by the Windows Manager. If you want to set a specific hint to your window, then you should check whether it exists in the supported auxiliary hints that are registered in the root window by the Windows Manager. Once you have added an auxiliary hint, you can get a new ID which is used to change the value and delete the hint. The Windows Manager sends a response message to the application on receiving the auxiliary hint change event.

elm_win_norender_pop()
elm_win_render()
Since (EFL) :
1.7
Since :
2.3

This pops (decrements) the norender counter on the window

Parameters:
objThe window object

See also:
elm_win_norender_push()
elm_win_norender_get()
elm_win_render()
Since (EFL) :
1.7
Since :
2.3

This pushes (increments) the norender counter on the window

Parameters:
objThe 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.

Gets the override state of a window.

Returns:
If true, the window is overridden.
Since :
2.3
void elm_win_override_set ( Evas_Object obj,
Eina_Bool  override 
)

Sets the override state of a window.

A window with override set to true will not be managed by the Window Manager. This means that no decorations of any kind will be shown for it, moving and resizing must be handled by the application, as well as the window visibility.

This should not be used for normal windows, and even for not so normal ones, it should only be used when there's a good reason and with a lot of care. Mishandling override windows may result situations that disrupt the normal workflow of the end user.

Parameters:
[in]overrideIf true, the window is overridden.

Set the window to be skipped by keyboard focus.

This sets the window to be skipped by normal keyboard input. This means a window manager will be asked not to focus this window as well as omit it from things like the taskbar, pager, "alt-tab" list etc. etc.

Call this and enable it on a window BEFORE you show it for the first time, otherwise it may have no effect.

Use this for windows that have only output information or might only be interacted with by the mouse or touchscreen, never for typing. This may have side-effects like making the window non-accessible in some cases unless the window is specially handled. Use this with care.

Parameters:
[in]objThe object.
[in]skipThe skip flag state ($true if it is to be skipped).

Examples:
win_example.c.
void elm_win_render ( Evas_Object obj)

This manually asks evas to render the window now

Parameters:
objThe 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.

Since :
2.3
void elm_win_resize_object_add ( Evas_Object obj,
Evas_Object subobj 
)

Adds 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]subobjThe resize object to add.
