void | YDialog::deleteEvent (YEvent *event) |
void | YSimpleEventHandler::deleteEvent (YEvent *event) |
Abstract base class for events to be returned upon UI::UserInput() and related functions.
YEvent::YEvent | ( | EventType | eventType = UnknownEvent | ) |
Constructor.
YEvent::~YEvent | ( | ) | [protected, virtual] |
Protected destructor - events can only be deleted via YDialog::deleteEvent(). The associated dialog will take care of this event and delete it when appropriate.
This desctructor is virtual to force a polymorph object so dynamic_cast<> can be used.
YDialog* YEvent::dialog | ( | ) | const [inline] |
Return the dialog this event belongs to or 0 if no dialog was set yet.
EventType YEvent::eventType | ( | ) | const [inline] |
Returns the event type.
void YEvent::invalidate | ( | ) | [protected] |
Mark this event as invalid. This cannot be undone.
bool YEvent::isValid | ( | ) | const |
Check if this event is valid. Events become invalid in the destructor.
virtual YItem* YEvent::item | ( | ) | const [inline, virtual] |
Return the YItem that corresponds to this event or 0 if there is none.
This default implementation always returns 0. Subclasses that actually return items should overwrite this method.
Reimplemented in YMenuEvent.
unsigned long YEvent::serial | ( | ) | const [inline] |
Returns the unique serial no. of this event. This is mainly useful for debugging.
void YEvent::setDialog | ( | YDialog * | dia | ) | [inline, protected] |
Set the dialog this event belongs to.
const char * YEvent::toString | ( | EventType | eventType | ) | [static] |
Returns the character representation of an event type.
const char * YEvent::toString | ( | EventReason | reason | ) | [static] |
Returns the character representation of an event reason.
virtual YWidget* YEvent::widget | ( | ) | const [inline, virtual] |
Returns the widget that caused this event or 0 if there is none.
This default implementation always returns 0. Subclasses that actually return widgets should overwrite this method.
Reimplemented in YWidgetEvent.
