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 Function Documentation

SoType SoButtonEvent::getClassTypeId (void) [static]

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

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoSpaceballButtonEvent, and SoMouseButtonEvent.

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

Returns the actual type id of an instantiated object.

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoSpaceballButtonEvent, and SoMouseButtonEvent.

void SoButtonEvent::initClass (void) [static]

Initialize the type information data.

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoSpaceballButtonEvent, and SoMouseButtonEvent.

void SoButtonEvent::setState (SoButtonEvent::Statestate)

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.

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

SbBool SoButtonEvent::enumToString (Stateenumval, 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.
