Class FocusManager

java.lang.Object

vaadinx.awt.KeyboardFocusManager

vaadinx.swing.FocusManager

All Implemented Interfaces:

Serializable

public class FocusManager
extends KeyboardFocusManager

Emulator for FocusManager: four statics and one constant, exactly as the JDK class is. Every query and command migrated code calls — getFocusOwner, focusNextComponent, … — is inherited from KeyboardFocusManager, which documents them.

Concrete, where the JDK's is abstract (a deliberate R_swing_is_truth deviation): getCurrentManager() has to hand out an instance, and the JDK's concrete subclass DefaultFocusManager is not ported.

Modifier and Type	Method	Description
static void	disableSwingFocusManager()	Deprecated.
static FocusManager	getCurrentManager()	The shared stateless facade; never null.
static boolean	isFocusManagerEnabled()	Deprecated.
static void	setCurrentManager(FocusManager manager)	WARN and ignore, same call as KeyboardFocusManager.setCurrentKeyboardFocusManager(KeyboardFocusManager): a user subclass's only overridable hooks are the ones this hierarchy WARNs on, so honouring the swap would imply more works than does.

Method Details

getCurrentManager

public static FocusManager getCurrentManager()

The shared stateless facade; never null.

setCurrentManager

public static void setCurrentManager(FocusManager manager)

WARN and ignore, same call as KeyboardFocusManager.setCurrentKeyboardFocusManager(KeyboardFocusManager): a user subclass's only overridable hooks are the ones this hierarchy WARNs on, so honouring the swap would imply more works than does.

disableSwingFocusManager

@Deprecated
public static void disableSwingFocusManager()

Deprecated.

Deprecated since 1.4 in the JDK and a no-op there for decades; there was never a Swing focus manager here to disable.

isFocusManagerEnabled

@Deprecated
public static boolean isFocusManagerEnabled()

Deprecated.

Always true — matching the JDK, where the flag has been pinned true since 1.4. Code gating on it takes the branch it takes on a modern JVM.
