Detailed Description

2D widget for manipulating a scalar bar

This class provides support for interactively manipulating the position, size, and orientation of a scalar bar. It listens to Left mouse events and mouse movement. It also listens to Right mouse events and notifies any observers of Right mouse events on this object when they occur. It will change the cursor shape based on its location. If the cursor is over an edge of the scalar bar it will change the cursor shape to a resize edge shape. If the position of a scalar bar is moved to be close to the center of one of the four edges of the viewport, then the scalar bar will change its orientation to align with that edge. This orientation is sticky in that it will stay that orientation until the position is moved close to another edge.

Member Function Documentation

static vtkScalarBarWidget* vtkScalarBarWidget::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkScalarBarWidget::GetClassName (  )  [virtual]

Reimplemented from vtkInteractorObserver.

static int vtkScalarBarWidget::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkInteractorObserver.

virtual int vtkScalarBarWidget::IsA ( const char *  name  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkInteractorObserver.

static vtkScalarBarWidget* vtkScalarBarWidget::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkInteractorObserver.

void vtkScalarBarWidget::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkInteractorObserver.

void vtkScalarBarWidget::SetScalarBarActor ( vtkScalarBarActor scalarbar  ) 

Get the ScalarBar used by this Widget. One is created automatically.

virtual vtkScalarBarActor* vtkScalarBarWidget::GetScalarBarActor (  )  [virtual]

Get the ScalarBar used by this Widget. One is created automatically.

virtual void vtkScalarBarWidget::SetEnabled ( int   )  [virtual]

Methods for turning the interactor observer on and off.

Reimplemented from vtkInteractorObserver.

static void vtkScalarBarWidget::ProcessEvents ( vtkObject object,
unsigned long  event,
void *  clientdata,
void *  calldata 
) [static, protected]

Handles the char widget activation event. Also handles the delete event.

Reimplemented from vtkInteractorObserver.

void vtkScalarBarWidget::OnLeftButtonDown (  )  [protected]

void vtkScalarBarWidget::OnLeftButtonUp (  )  [protected]

void vtkScalarBarWidget::OnRightButtonDown (  )  [protected]

void vtkScalarBarWidget::OnRightButtonUp (  )  [protected]

void vtkScalarBarWidget::OnMouseMove (  )  [protected]

int vtkScalarBarWidget::ComputeStateBasedOnPosition ( int  X,
int  Y,
int *  pos1,
int *  pos2 
) [protected]

void vtkScalarBarWidget::SetCursor ( int  State  )  [protected]
