The SoButtonEvent class is the base class for all button events.
The event classes which results from the user pushing buttons on some device (keyboard, mouse or spaceball) all inherit this class. The SoButtonEvent class contains methods for setting and getting the state of the button(s).
enum SoButtonEvent::State |
SoButtonEvent::SoButtonEvent | ( | void | ) |
Constructor.
References UNKNOWN.
Referenced by getTypeId(), initClass(), SoKeyboardEvent::initClass(), SoMouseButtonEvent::initClass(), SoSpaceballButtonEvent::initClass(), SoSpaceballButtonEvent::isButtonPressEvent(), SoSpaceballButtonEvent::isButtonReleaseEvent(), SoKeyboardEvent::isKeyPressEvent(), and SoKeyboardEvent::isKeyReleaseEvent().
|
virtual |
Destructor.
|
virtual |
Returns the actual type id of an instantiated object.
Reimplemented from SoEvent.
Reimplemented in SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.
References SoButtonEvent().
void SoButtonEvent::setState | ( | SoButtonEvent::State | state | ) |
Set the state of the button which the user interacted with.
This method is used from the window specific device classes when translating events to the generic Coin library.
SoButtonEvent::State SoButtonEvent::getState | ( | void | ) | const |
Returns the state of the button which is the cause of the event, i.e. whether it was pushed down or released.
Referenced by SoMouseButtonEvent::isButtonPressEvent(), and SoMouseButtonEvent::isButtonReleaseEvent().
|
static |
Initialize the type information data.
