Base class for all events defined in the Gishur package. GishurEvents are
based on AWTEvents
and can so dispatched by standard AWT
Components. GishurEvent assumes a few things about standard AWT events, so
if that changes, an update of GishurEvent should be enough to correct the
problem. GishurEvent mirrors the event masks for standard awt events as int
values in order to enable correct event enabeling. Gishur events use the
upper 20 bits of the event-id as event mask to check fast, if a event is
enabled or not. This is enough for 20 types of events, the other 12 bits of
the 32 bit integer are used to specify the type of the event. This system
works until the maximum reserved id for awt-events is smaller than 4096
(at this time (JDK 1.2) its 1999). AWT event masks can be much greater! To
ensure that they fit into an integer, Gishur uses the event mask defined
by this class rather than the event masks defined by AWTEvent
.
The enable/disable check for internal awt events is performed awt-compatibel,
so this should work anyway.

static int |
GISHUR_EVENT_MASK

GISHUR_ID_MASK
Mask for the type-part of an event id - this should be the complement of GISHUR_EVENT_MASK . |
static int |
MAX_EVENT_TYPES
