Overview

The EFL UTIL WINDOW PROPERTY API provides functions to set/get properties of windows such as the notification level, the screen mode and the brightness.

Notification Level

Tizen windows have a layer hierarchy. Window layers are logical containers used to control the window stack order.
Among these, there is a notification layer for windows that need to appear above regular windows like emergency popups.
And the notification level is provided for layering between notification windows.
This works ONLY for NOTIFICATION type window.

Screen Mode

By setting the Screen Mode on a window, you can prevent the screen from being turned off automatically by the timer while the window is visible on the screen.

Brightness

By setting the Brightness on a window, you can change the brightness of the screen.

efl_util_notification_level_e *  level 
)

Gets the priority level for the specified notification window.

Since :
2.3
Remarks:
This API can be used for a notification type window only. Up to the version 2.4, it supports as async APIs. But it is synchronous call since Tizen 3.0
Parameters:
[in]windowThe EFL window
[out]levelThe notification window level
Returns:
0 on success, otherwise a negative error value
Return values:
EFL_UTIL_ERROR_NONESuccessful
EFL_UTIL_ERROR_INVALID_PARAMETERInvalid parameter
EFL_UTIL_ERROR_NOT_SUPPORTED_WINDOW_TYPEWindow type not supported

Gets the user's preferred brightness of the specified window.

Since :
3.0
Parameters:
[in]windowThe EFL window
[out]brightnessThe preferred brightness
Returns:
0 on success, otherwise a negative error value
Return values:
EFL_UTIL_ERROR_NONESuccessful
EFL_UTIL_ERROR_INVALID_PARAMETERInvalid parameter

int efl_util_set_window_brightness ( Evas_Object *  window,
int  brightness 
)

Sets the user's preferred brightness of the specified window.

This API is useful when the application need to change the brightness of the screen when it is appeared on the screen. If the application sets the brightness 0 to 100 to its window and the application window is shown wholly or partially, the window manager requests the display system to change the brightness of the screen using user's preferred brightness. If the window is no longer shown, then the window manger request the display system to go back to default brightness. If the brightness is less than 0, this means to use the default screen brightness.

Since :
3.0
Privilege Level:
public
Privilege:
http://tizen.org/privilege/display
Remarks:
This API needs the privilege. If the application which is not get the privilege use this API, the window manager generates the permission deny error.
Parameters:
[in]windowThe EFL window
[in]brightnessThe preferred brightness
Returns:
0 on success, otherwise a negative error value
Return values:
EFL_UTIL_ERROR_NONESuccessful
EFL_UTIL_ERROR_PERMISSION_DENIEDPermission denied
EFL_UTIL_ERROR_INVALID_PARAMETERInvalid parameter
EFL_UTIL_ERROR_OUT_OF_MEMORYOut of memory
See also:
efl_util_get_window_brightness()
int efl_util_set_window_opaque_state ( Evas_Object *  window,
int  opaque 
)

Sets the alpha window's visual state to opaque state.

This API sets the alpha window's visual state to opaque state. If the alpha window sets the visual state to the opaque, then the window manager could handle it as the opaque window while calculating visibility. This API will have no effect when used by a non-alpha window.

Since :
2.4
Parameters:
[in]windowThe EFL window
[in]opaqueThe value that indicates whether the window has set a visual state to opaque (0: unset, 1: set)
Returns:
0 on success, otherwise a negative error value
Return values:
EFL_UTIL_ERROR_NONESuccessful
EFL_UTIL_ERROR_INVALID_PARAMETERInvalid parameter
int efl_util_set_window_screen_mode ( Evas_Object *  window,
efl_util_screen_mode_e  mode 
)

Sets the window's screen mode.

This API is useful when the application need to keep the display turned on. If the application set the mode to EFL_UTIL_SCREEN_MODE_ALWAYS_ON to its window and the window is shown wholly or partially, the window manager requests the display system to keep the display on as long as the window is shown. If the window is no longer shown, then the window manger request the display system to go back to normal operation. Default screen mode of window is EFL_UTIL_SCREEN_MODE_DEFAULT.
