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.
Since:
JavaFX 2.0

* #### GRAPHICS public static final [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") GRAPHICS Indicates that JavaFX classes providing graphics capabilities are available on this platform. Since: JavaFX 8.0 * #### CONTROLS public static final [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") CONTROLS Indicates that JavaFX classes providing UI controls are available on this platform. Since: JavaFX 8.0 * #### MEDIA public static final [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") MEDIA Indicates that the javafx.scene.media package is available on this platform. Since: JavaFX 8.0 * #### WEB public static final [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") WEB Indicates that the javafx.scene.web packages is available on this platform. Since: JavaFX 8.0 * #### SWT public static final [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/util/FXPermission.html "class in javafx.util") "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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") UNIFIED_WINDOW Indicates that a system supports [StageStyle.UNIFIED](../../javafx/stage/StageStyle.html#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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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](../../javafx/application/ConditionalFeature.html "enum in javafx.application") 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. Since: JavaFX 8.0Method Detail
* #### values public static [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application")[] values() Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: for (ConditionalFeature c : ConditionalFeature.values()) System.out.println(c); Returns: an array containing the constants of this enum type, in the order they are declared * #### valueOf public static [ConditionalFeature](../../javafx/application/ConditionalFeature.html "enum in javafx.application") valueOf([String](../../java/lang/String.html "class in java.lang") name) Returns the enum constant of this type with the specified name. The string must match _exactly_ an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.) Parameters: `name` \- the name of the enum constant to be returned. Returns: the enum constant with the specified name Throws: `[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if this enum type has no constant with the specified name `[NullPointerException](../../java/lang/NullPointerException.html "class in java.lang")` \- if the argument is null
