Field Detail

KEYEVENTF_EXTENDEDKEY

public static final int KEYEVENTF_EXTENDEDKEY

If specified, the scan code was preceded by a prefix byte that has the value 0xE0 (224).

See Also:

Constant Field Values

KEYEVENTF_KEYUP

public static final int KEYEVENTF_KEYUP

If specified, the key is being released. If not specified, the key is being pressed.

See Also:

Constant Field Values

KEYEVENTF_UNICODE

public static final int KEYEVENTF_UNICODE

If specified, the system synthesizes a VK_PACKET keystroke. The wVk parameter must be zero. This flag can only be combined with the KEYEVENTF_KEYUP flag. For more information, see the Remarks section.

See Also:

Constant Field Values

KEYEVENTF_SCANCODE

public static final int KEYEVENTF_SCANCODE

If specified, wScan identifies the key and wVk is ignored.

See Also:

Constant Field Values

wVk

public WinDef.WORD wVk

A virtual-key code. The code must be a value in the range 1 to 254. If the dwFlags member specifies KEYEVENTF_UNICODE, wVk must be 0.

wScan

public WinDef.WORD wScan

A hardware scan code for the key. If dwFlags specifies KEYEVENTF_UNICODE, wScan specifies a Unicode character which is to be sent to the foreground application.

dwFlags

public WinDef.DWORD dwFlags

Specifies various aspects of a keystroke. This member can be certain combinations of the following values.

time

public WinDef.DWORD time

The time stamp for the event, in milliseconds. If this parameter is zero, the system will provide its own time stamp.

dwExtraInfo

public BaseTSD.ULONG_PTR dwExtraInfo

An additional value associated with the keystroke. Use the GetMessageExtraInfo function to obtain this information.

Method Detail

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
