Detailed Description
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).

Member Enumeration Documentation
enum SoButtonEvent::State
This gives the actual state of the button.
Enumerator
- UP
Button has been released.
- DOWN
Button has been pressed down.
- UNKNOWN
The state of the button is unknown.
Constructor & Destructor Documentation
SoButtonEvent::SoButtonEvent (void)
Constructor.
SoButtonEvent::~SoButtonEvent () [virtual]
Destructor.
Member Function Documentation
SoType SoButtonEvent::getTypeId (void) const [virtual]
Returns the actual type id of an instantiated object.
Reimplemented from SoEvent.
Reimplemented in SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.
void SoButtonEvent::initClass (void) [static]
Initialize the type information data.
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.

getState()
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.

wasShiftDown(), wasCtrlDown(), wasAltDown(), getPosition(), getTime()
SbBool SoButtonEvent::enumToString (State enumval, SbString & stringrep) [static]
Converts from an enum value of type SoButtonEvent::State to a string containing the enum symbol.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
