Class Screen

java.lang.Object
javafx.stage.Screen
public final class Screen extends Object
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();

JavaFX 2.0

Method Details

getPrimary

public static Screen getPrimary()
The primary Screen.
Returns:
the primary screen

getScreens

public static ObservableList<Screen> getScreens()
The observable list of currently available Screens.
Returns:
observable list of currently available screens

getScreensForRectangle

public static ObservableList<Screen> getScreensForRectangle(double x, double y, double width, double height)
Returns a ObservableList of Screens that intersects the provided rectangle.
Parameters:
x - the x coordinate of the upper-left corner of the specified rectangular area
y - the y coordinate of the upper-left corner of the specified rectangular area
width - the width of the specified rectangular area
height - the height of the specified rectangular area
Returns:
a ObservableList of Screens for which Screen.bounds intersects the provided rectangle

getScreensForRectangle

public static ObservableList<Screen> getScreensForRectangle(Rectangle2D r)
Returns a ObservableList of Screens that intersects the provided rectangle.
Parameters:
r - The specified Rectangle2D
Returns:
a ObservableList of Screens for which Screen.bounds intersects the provided rectangle

getBounds

public final Rectangle2D 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.
Returns:
The bounds of this Screen

getVisualBounds

public final Rectangle2D 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.
Returns:
The visual bounds of this Screen

getDpi

public final double getDpi()
Gets the resolution (dots per inch) of this Screen.
Returns:
The resolution of this Screen

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.
Returns:
the recommended output scale factor for the screen.
Since:
9

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.
Returns:
the recommended output scale factor for the screen.
Since:
9

hashCode

public int hashCode()
Returns a hash code for this Screen object.
Overrides:
hashCode in class Object
Returns:
a hash code for this Screen object.

equals

public boolean equals(Object obj)
Indicates whether some other object is "equal to" this one.
Overrides:
equals in class Object
Parameters:
obj - the reference object with which to compare.
Returns:
true if this object is equal to the obj argument; false otherwise.

toString

public String toString()
Returns a string representation of this Screen object.
Overrides:
toString in class Object
Returns:
a string representation of this Screen object.
