Enum Class ConditionalFeature

java.lang.Object
java.lang.Enum<ConditionalFeature>
javafx.application.ConditionalFeature
All Implemented Interfaces:
Serializable, Comparable<ConditionalFeature>, Constable
public enum ConditionalFeature extends Enum<ConditionalFeature>
Defines a set of conditional (optional) features. These features may not be available on all platforms. An application that wants to know whether a particular feature is available may query this using the Platform.isSupported() function. Using a conditional feature on a platform that does not support it will not cause an exception. In general, the conditional feature will just be ignored. See the documentation for each feature for more detail.

JavaFX 2.0

  • Enum Constant Details

    • GRAPHICS

      public static final ConditionalFeature GRAPHICS
      Indicates that JavaFX classes providing graphics capabilities are available on this platform.
      Since:
      JavaFX 8.0

    • CONTROLS

      public static final ConditionalFeature CONTROLS
      Indicates that JavaFX classes providing UI controls are available on this platform.
      Since:
      JavaFX 8.0

    • MEDIA

      public static final ConditionalFeature MEDIA
      Indicates that the javafx.scene.media package is available on this platform.
      Since:
      JavaFX 8.0

    • WEB

      public static final ConditionalFeature WEB
      Indicates that the javafx.scene.web packages is available on this platform.
      Since:
      JavaFX 8.0

    • SWT

      public static final ConditionalFeature SWT
      Indicates that SWT integration is available on the platform. This tests for SWT integration with JavaFX, but does not test for the presence of the full SWT library.
      Since:
      JavaFX 8.0

    • SWING

      public static final ConditionalFeature SWING
      Indicates that the Swing library is present in the Java Runtime Environment and that Swing integration with JavaFX is available on the platform.
      Since:
      JavaFX 8.0

    • FXML

      public static final ConditionalFeature FXML
      Indicates that XML libraries are present in the JRE and that the FXML API is available on the platform. Note that it is possible for FXML APIs to be present but unusable if the underlying Java Runtime Environment does not have XML support. In this case Platform.isSupported(ConditionalFeature.FXML) wll return false.
      Since:
      JavaFX 8.0

    • SCENE3D

      public static final ConditionalFeature SCENE3D
      Indicates that 3D is available on the platform. If an application attempts to use 3D transforms or a 3D camera on a platform that does not support 3D, then the transform or camera is ignored; it effectively becomes the identity transform.

    • EFFECT

      public static final ConditionalFeature EFFECT
      Indicates that filter effects are available on the platform. If an application uses an effect on a platform that does not support it, the effect will be ignored.

    • SHAPE_CLIP

      public static final ConditionalFeature SHAPE_CLIP
      Indicates that clipping against an arbitrary shape is available on the platform. If an application specifies a clip node on a platform that does not support clipping against an arbitrary shape, the node will be clipped to the bounds of the specified clip node rather than its geometric shape.

    • INPUT_METHOD

      public static final ConditionalFeature INPUT_METHOD
      Indicates that text input method is available on the platform. If an application specifies an input method on a platform that does not support it, the input method will be ignored.

    • TRANSPARENT_WINDOW

      public static final ConditionalFeature TRANSPARENT_WINDOW
      Indicates that the system supports full window transparency. Transparent windows will have only limited or no functionality on a platform that doesn't support it.

      Currently, this support is available on all desktop platforms except Linux systems without the XComposite extension. The XShape extension is used in that case, so the window edges are aliased.

      If a security manager is present, the application must have the FXPermission "createTransparentWindow" in order to create a transparent window. If the application doesn't have the required permission, it won't be able to use this feature; it will appear as if the the platform doesn't support transparent windows, and Platform.isSupported(TRANSPARENT_WINDOW) will return false.

      Since:
      JavaFX 2.2

    • UNIFIED_WINDOW

      public static final ConditionalFeature UNIFIED_WINDOW
      Indicates that a system supports StageStyle.UNIFIED

      NOTE: Currently, supported on:

      • Windows Vista+: a window is completely filled with the frozen glass effect
      • Mac OS X: a window has the brushed-metal textured background
      Since:
      JavaFX 8.0

    • TWO_LEVEL_FOCUS

      public static final ConditionalFeature TWO_LEVEL_FOCUS
      Indicates whether or not controls should use two-level focus. Two-level focus is when separate operations are needed in some controls to first enter a control and then to perform operations on the control. Two-level focus is needed on devices that provide directional arrow keys and a select key but do not provide keys for navigating between one control and another. On these devices a focused control may be either internally focused - in which case arrow keys operate on the control - or externally focused, in which case arrow keys are used to navigate focus to other controls.

      On embedded platforms JavaFX makes an attempt to initialize this ConditionalFeature based on what input peripherals are attached. On desktop platforms this ConditionalFeature will typically default to false.

      Since:
      JavaFX 8.0

    • VIRTUAL_KEYBOARD

      public static final ConditionalFeature VIRTUAL_KEYBOARD
      Indicates whether an on-screen virtual keyboard is used for text input.

      On embedded platforms JavaFX makes an attempt to initialize this ConditionalFeature based on what input peripherals are attached. On desktop platforms this ConditionalFeature will typically default to false.

      Since:
      JavaFX 8.0

    • INPUT_TOUCH

      public static final ConditionalFeature INPUT_TOUCH
      Indicates whether or not a touch screen is attached to the device on which JavaFX in running.

      On embedded platforms JavaFX makes an attempt to initialize this ConditionalFeature based on what input peripherals are attached. On desktop platforms this ConditionalFeature will typically default to false.

      Since:
      JavaFX 8.0

    • INPUT_MULTITOUCH

      public static final ConditionalFeature INPUT_MULTITOUCH
      Indicates whether or not a touch screen providing multi-touch input is attached to the device on which JavaFX in running.

      On embedded platforms JavaFX makes an attempt to initialize this ConditionalFeature based on what input peripherals are attached. On desktop platforms this ConditionalFeature will typically default to false.

      If INPUT_MULTITOUCH is available then INPUT_TOUCH is also available.

      Since:
      JavaFX 8.0

    • INPUT_POINTER

      public static final ConditionalFeature INPUT_POINTER
      Indicates whether or not a relative motion pointer device such as a mouse, trackpad or trackball is attached.

      On embedded platforms JavaFX makes an attempt to initialize this ConditionalFeature based on what input peripherals are attached. On desktop platforms this ConditionalFeature will typically default to true.
