bool Dali::Window::SetBrightness ( int  brightness)

Sets preferred brightness of the window.

This API is useful when the application needs to change the brightness of the screen when it is appeared on the screen. If the brightness has been set and the window is shown, the window manager requests the display system to change the brightness to the provided value. If the window is no longer shown, then the window manager requests the display system to go back to default brightness. A value less than 0 results in default brightness and a value greater than 100 results in maximum brightness.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]brightnessThe preferred brightness (0 to 100).
Returns:
True if no error occurred, false otherwise.
Privilege Level:
public
Privilege:
http://tizen.org/privilege/display
void Dali::Window::SetClass ( std::string  name,
std::string  klass 
)

Sets the window name and class string.

Since:
2.4, DALi version 1.0.0
Parameters:

[in]klassThe class of the window
void Dali::Window::SetIndicatorBgOpacity ( IndicatorBgOpacity  opacity)

This sets the opacity mode of indicator bar.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]opacityThe opacity mode
void Dali::Window::SetInputRegion ( const Rect< int > &  inputRegion)

Sets a region to accept input events.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]inputRegionThe region to accept input events.
bool Dali::Window::SetNotificationLevel ( NotificationLevel::Type  level)

Sets a priority level for the specified notification window.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]levelThe notification window level.
Returns:
True if no error occurred, false otherwise.
Privilege Level:
public
Privilege:
http://tizen.org/privilege/window.priority.set
Remarks:
This can be used for a notification type window only. The default level is NotificationLevel::NONE.
void Dali::Window::SetOpaqueState ( bool  opaque)

Sets a transparent window's visual state to opaque.

If a visual state of a transparent window is opaque, then the window manager could handle it as an opaque window when calculating visibility.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]opaqueWhether the window's visual state is opaque.
Remarks:
This will have no effect on an opaque window. It doesn't change transparent window to opaque window but lets the window manager know the visual state of the window.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]positionThe new window position

bool Dali::Window::SetScreenOffMode ( ScreenOffMode::Type  screenOffMode)

Sets a window's screen off mode.

This API is useful when the application needs to keep the display turned on. If the application sets the screen mode to #Dali::Window::ScreenOffMode::NEVER to its window and the window is shown, 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 manager requests the display system to go back to normal operation.

Since:
4.0, DALi version 1.2.60
Parameters:
[in]screenOffModeThe screen mode.
Returns:
True if no error occurred, false otherwise.
