Constructor Detail

HKeyCapabilities

protected HKeyCapabilities()

An interoperable application shall not subclass the HKeyCapabilities class.

Creates an HKeyCapabilities object. See the class description for details of constructor parameters and default values.

This method is protected to allow the platform to override it in a different package scope.

Method Detail

getInputDeviceSupported

public static boolean getInputDeviceSupported()

Determine if keyboard input functionality exists in the system. Note that this functionality may be provided through a "virtual" keyboard.

Returns:

true if keyboard input functionality exists in the system, false otherwise.

See Also:

HRcCapabilities.getInputDeviceSupported()

isSupported

public static boolean isSupported(int keycode)

Queries whether the system keyboard can generate an event of the given type. Note that this method does not distinguish between key codes which can only be generated via a virtual keyboard and key codes generated as a result of "real" key presses.

Parameters:

keycode - the keycode to query e.g. VK_SPACE

Returns:

true if events with the given key code can (ever) be generated on this system, false otherwise.
