Screen class in java

Screen class in java

Describes the characteristics of a graphics destination such as monitor. In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of the Screen objects are relative to the Screen.primary . For example:

 Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds(); //set Stage boundaries to visible bounds of the main screen stage.setX(primaryScreenBounds.getMinX()); stage.setY(primaryScreenBounds.getMinY()); stage.setWidth(primaryScreenBounds.getWidth()); stage.setHeight(primaryScreenBounds.getHeight()); stage.show();

getPrimary

getScreens

getScreensForRectangle

public static ObservableListScreen> getScreensForRectangle​(double x, double y, double width, double height)

getScreensForRectangle

public static ObservableListScreen> getScreensForRectangle​(Rectangle2D r)

getBounds

Gets the bounds of this Screen . The bounds will be reported adjusted for the outputScale so that resizing a Window with these bounds and the same outputScale as this Screen will cover the entire screen.

getVisualBounds

Gets the visual bounds of this Screen . These bounds account for objects in the native windowing system such as task bars and menu bars. These bounds are contained by Screen.bounds .

getDpi

public final double getDpi​()

getOutputScaleX

public final double getOutputScaleX​()

Gets the recommended output scale factor of this Screen in the horizontal ( X ) direction. This scale factor should be applied to a scene in order to compensate for the resolution and viewing distance of the output device. The visual bounds will be reported relative to this scale factor.

getOutputScaleY

public final double getOutputScaleY​()

Gets the recommended output scale factor of this Screen in the vertical ( Y ) direction. This scale factor will be applied to the scene in order to compensate for the resolution and viewing distance of the output device. The visual bounds will be reported relative to this scale factor.

Screen class in java

This class implements a fixed size visible area. It shows pixel data stored in a Surface object. The Surface object holding data shown on the Screen is called the ‘main Surface’.

use_palette

public boolean use_palette

Palette info. The palette is modified by changing the ‘palette’ array. In order to commit your palette changes, you must call the ‘updatePalette’ method. If we are running in direct-color, the palette array is null, and the use_palette flag is false. Please do not change the number of entries in the palette array.
