Class KeyEvent

public class KeyEvent extends GtkEvent

Deprecated: This class is part of the java-gnome 2.x family of libraries, which, due to their inefficiency and complexity, are no longer being maintained and have been abandoned by the java-gnome project. Signal handling an connection has been completely re-implemented in java-gnome 4.0, so you will need to refactor any code attempting to use this class.

This event object is used to identify when a key has been pressed and released. In particular, it allows you to get at which key was pressed - see getKeyval.

Constructor Detail

KeyEvent

public KeyEvent(Object source, KeyEvent.Type type, EventKey gdkEvent)

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Construct a KeyEvent object.

Method Detail

getKeyval

public int getKeyval()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the key value. Example:
       if (key == KeyValue.Return) {
           ...
       }
 

Returns: an int, the key value. See KeyValue for the comprehensive list of values.

getLength

public int getLength()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the length of the String that resulted from this keypress (see getString).

Returns: int

getModifierKey

public ModifierType getModifierKey()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the modifier key used.

Returns: (see ModifierType)

getString

public String getString()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Get the "null-terminated multi-byte string containing the composed characters resulting from the key press".

FIXME: Isn't null termination hidden in Java? And, in any case, characters in Strings in Java are multi-byte. So does this work right nor not?

Returns: String the character(s) resulting from the key press.

isOfType

public boolean isOfType(KeyEvent.Type test)

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Test to compare events.
