Detailed Description

SoFocus is a general facility to detect focus changes.

The information, if a sub graph has the focus, is passed to the inventor state. SoFocus is a general facility to detect focus changes. The information, if a sub graph has the focus, is passed to the inventor state.

Constructor & Destructor Documentation

SoFocus()

SoFocus::SoFocus

(

)

Constructor.

~SoFocus()

SoFocus::~SoFocus ( )

overrideprotected

Protected destructor.

Member Function Documentation

activeChanged()

void SoFocus::activeChanged ( SoField *  )

protected

GLRender()

void SoFocus::GLRender ( SoGLRenderAction *  action )

overrideprotected

React to render action -> pass focus to state.

handleEvent()

void SoFocus::handleEvent ( SoHandleEventAction *  action )

override

handle event is reimplemented to handle the mouse events.

The events are not consumed, so that following modules in the scene graph can handle them.

hasFocusChanged()

void SoFocus::hasFocusChanged ( SoField *  )

protected

initClass()

static void SoFocus::initClass ( )

static

Initializes this class (called on dll initialization).

setFocusState()

void SoFocus::setFocusState	(	FocusState	state,
		bool	updateField = true
	)

Set focus state for this module.

If updateField is true, the field "hasFocus" is updated.

Member Data Documentation

active

SoSFBool SoFocus::active

! Fields

Should this module change the focus state?

Definition at line 43 of file SoFocus.h.

hasFocus

SoSFBool SoFocus::hasFocus

Current state (has focus or has no focus).

Definition at line 46 of file SoFocus.h.

normClickCoords

SoSFVec2f SoFocus::normClickCoords

Display the normalized coordinates of the click event that caused the focus state.

This is useful if one Viewer has several regions that should be activated separately. For example, if a SoView2d has more than 1 slice, SoView2DBorder is drawn several times. normClickCoords can be used to determine which border should be highlighted.

supportWheelEvents

SoSFBool SoFocus::supportWheelEvents

Should this module support mouse wheel events?

Definition at line 49 of file SoFocus.h.
