Detailed Description

TFViewWidget, a class for handling interaction in 2D projections of transfer function domain.

Definition at line 31 of file TFViewWidget.h.

Event & constraint mapper.

All widgets have the default event of: gutz::GUTZ_LEFT_MOUSE -> MOVE you may want to nuke this event if it isn't applicable: delEvent(gutz::GUTZ_LEFT_MOUSE); event keys are defined in: gutzKeyMouse.h

enum  WIGET_BEHAVIORS { NO_EVENT = 0, MOVE, ROTATE, WB_LAST }
void addEvent (const unsigned int key, const unsigned int event, const ConstraintSP cnst=new Constraint())
 addEvent. constraint defaults to "Free Move" constraint

unsigned int getEvent (const gutz::MouseEvent &me) const
 getEvent, returns the event if one is defined, returns NO_EVENT if the mouse is up works for both: gutz::MouseEvent and gutz::MouseMoveEvent This function is usefull in implementation, externally use getEvent(unsigned int).

unsigned int getEvent (unsigned int key) const
 what is the event assigned to a key

void delEvent (const unsigned int key)
 delete an event from the event map

void nukeEvents ()
 delete all events from the event map

gutz::EventKeyMap getEvents () const
void setEvents (const gutz::EventKeyMap &eventMap)
ConstraintMap getConstraints () const
void setConstraints (const ConstraintMap &cnstMap)

Axes

May not always be meaningfull, but it is very convenient for this widget to store this information, even though that exposes (some of) the "symantics" of this widget, it is called TFViewWidget after all :).


Mostly done to save time and effort spent in keeping around a map from TFViewWidgets -> axies and visa-versa.
By Default axes == (0,1)

gutz::vec2i getAxes () const
gutz::vec2i setAxes (const gutz::vec2i &axes)

TFSurface set/get/del

The tf surface should be the same object as the SurfaceWidget contained in the FrameWidget level of the hierarchy

void setTFSurface (TFSurfaceWidget *sw)
TFSurfaceWidgetSP getTFSurface () const
void delTFSurface ()

Behaviors

virtual void drawDef (const gutz::RenderEvent &r)
 draw just forwards event to children, this widget is a composite so we don't draw anything ourselves.

virtual bool mouseChild (WidgetItem *child, const gutz::MouseEvent &me)
 child mousing, right now the Frame doesn't do anything with the mouse event, only the move event.

virtual bool moveChild (WidgetItem *child, const gutz::MouseMoveEvent &mme)
 override of FrameWidget::moveChild


Clones

WidgetItem * clone () const
virtual FrameWidget * cloneFrame () const
 notice that this ISN'T pure virtual, rather it is virtual since we only need to clone our sub-widgets, however if you sub-class from this, you REALLY need to override this clone.


Modify the dimensions

With some higher-level symantics, none of these are well tested yet!

virtual void setDims (float width, float height)
 dimensions: width & height

float getWidth () const
 Width.

virtual void setWidth (float width)
float getHeight () const
 Height.

virtual void setHeight (float height)
gutz::vec3f getCenter () const
 Center.

virtual void setCenter (const gutz::vec3f &center)

Behaviors from PolygonWidget

Notice that we dont define our own move() and mouse(), since we don't render any geometry of our own, all events will come through our children.

virtual void delChild (WidgetItem *child)
 override of delChild from WidgetItem


Plane get

get the gutz::plane defined by the frame

gutz::planef getPlane () const

Surface set/get/del

void setSurface (SurfaceWidget *sw)
SurfaceWidgetSP getSurface () const
virtual void delSurface ()

Transform Widget

virtual void scale (const gutz::vec3f scale)
virtual void translate (const gutz::vec3f trans)
virtual void applyXform (gutz::mat4f xf)
 apply a 4x4 transformation matrix, must be defined by a sub-class.


Node/Edge set/get

carefull, the set may have no "meaning", may not be appropriate for subclass behaviors.

The gets are very usefull though.

int getNodeSize () const
NodeWidgetSP getNode (int idx) const
virtual void setNode (int idx, NodeWidgetSP n)
virtual void addNode (NodeWidgetSP n)
int getEdgeSize () const
EdgeWidgetSP getEdge (int idx) const
virtual void setEdge (int idx, EdgeWidgetSP e)
virtual void addEdge (EdgeWidgetSP e)

Events duplicated from <Renderable>.

These are duplicated to insure/ease framework issues, notice that mouse and move handle the "check with parent" and mouseDef(), moveDef() are what actually implement the behavior.

void draw (const gutz::RenderEvent &r)
 main draw event...

bool mouse (const gutz::MouseEvent &me)
 a mouse event...

virtual bool mouseDef (const gutz::MouseEvent &me)
 override this one to implement mouse behavior

bool move (const gutz::MouseMoveEvent &mme)
 a move event, checks with parent, then calls moveDef().

virtual bool moveDef (const gutz::MouseMoveEvent &mme)
 override this one to implement move behavior


Parent/Child management

virtual void addChild (WidgetItem *child)
 a child was added

virtual void setParent (WidgetItem *parent)
 a (new?) parent now owns you :)


Some appearance management

ColorWStateSP getColor () const
void setColor (ColorWState *const color)

Draw on/off.

bool isOn () const
void setOn (bool yes)

Delete.

Does this object need to be removed from a render list? This means that the object is finished and anyone with a smart pointer to it needs to delete the smart pointer and stop using the renderable.

bool needsDelete () const
void setDelete (bool yes)

Interaction Functions

Return true if the event was for you.

By default interaction is forwarded to your protected manipulator (_manip). To use it just apply it in your draw function. However, if you don't add any events or call setManipEventsDefault(), you won't have any interaction. Override these functions in your base class to implement custom behaviors.

virtual bool key (unsigned char k, int x, int y)

Selected

Is this object currently selected?

virtual void setSelected (bool yes)
bool isSelected () const

Manipulator Interface

gutz::Manip * getManip () const
void setManip (gutz::Manip *const m)
void setManipEventsDefault ()
 you have to call this to enable default interaction, OR customize the manipulators events yourself.


Signals

gutz::Signal< const gutz::vec2i &,
const gutz::vec2f & > 		insertElementEvent
 insertElementEvent(const gutz::vec2i axes, const vec2f& pos) signal.


Signals

see gutz::Signal for API details

gutz::Signal< gutz::planef > planeChanged
 signal: planeChanged(gutz::planef p);

insertElementEvent(const gutz::vec2i axes, const vec2f& pos) signal.

The surface of the transfer function was clicked, and that event maps to the insert event. The first parameter is the axes idicies of the view that emmited the event, and the last one is the (0,1) range position of that click within the TFViewWidgets frame.
