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).

SoEventCallback, SoHandleEventAction

enum SoButtonEvent::State

This gives the actual state of the button.

Enumerator

Button has been released.
Button has been pressed down.
The state of the button is unknown.

Constructor.

Destructor.

SoType SoButtonEvent::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoButtonEvent::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoEvent. This is used for runtime type checking and 'downward' casting.

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.

See also

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.

See also

wasShiftDown(), wasCtrlDown(), wasAltDown(), getPosition(), getTime()

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.
