| org.eclipse.swt.events.TypedEvent
 org.eclipse.swt.events.KeyEvent
All known Subclasses: org.eclipse.swt.events.VerifyEvent, org.eclipse.swt.events.TraverseEvent,
| KeyEvent | | public class KeyEvent extends TypedEvent (Code) | | Instances of this class are sent as a result of
keys being pressed and released on the keyboard.
When a key listener is added to a control, the control
will take part in widget traversal. By default, all
traversal keys (such as the tab key and so on) are
delivered to the control. In order for a control to take
part in traversal, it should listen for traversal events.
Otherwise, the user can traverse into a control but not
out. Note that native controls such as table and tree
implement key traversal in the operating system. It is
not necessary to add traversal listeners for these controls,
unless you want to override the default traversal.

| Field Summary | |
| public char | character
the character represented by the key that was typed. | | public boolean | doit
A flag indicating whether the operation should be allowed. | | public int | keyCode
the key code of the key that was typed,
as defined by the key code constants in class SWT.
When the character field of the event is ambiguous, this field
contains the unicode value of the original character. | | final static long | serialVersionUID
| | public int | stateMask
the state of the keyboard modifier keys at the time
the event was generated, as defined by the key code
constants in class SWT. |
| Constructor Summary | |
| public | KeyEvent(Event e)
Constructs a new instance of this class based on the
information in the given untyped event. |
| Method Summary | |
| public String | toString()
Returns a string containing a concise, human-readable
description of the receiver. |
| character | | public char character(Code) | | the character represented by the key that was typed.
This is the final character that results after all modifiers have been
applied. For example, when the user types Ctrl+A, the character value
is 0x01. It is important that applications do not attempt to modify the
character value based on a stateMask (such as SWT.CTRL) or the resulting
character will not be correct.
|
| doit | | public boolean doit(Code) | | A flag indicating whether the operation should be allowed.
Setting this field to false will cancel the operation.
|
| keyCode | | public int keyCode(Code) | | the key code of the key that was typed,
as defined by the key code constants in class SWT.
When the character field of the event is ambiguous, this field
contains the unicode value of the original character. For example,
typing Ctrl+M or Return both result in the character '\r' but the
keyCode field will also contain '\r' when Return was typed.

| serialVersionUID | | final static long serialVersionUID(Code) | | |
| stateMask | | public int stateMask(Code) | | the state of the keyboard modifier keys at the time
the event was generated, as defined by the key code
constants in class SWT.
