Detailed Description

An interactor for chart views It observes the user events (mouse events) and propagates them to the scene. If the scene doesn't eat the event, it is propagated to the interactor style superclass.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkInteractorStyle.

void vtkContextInteractorStyle::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 vtkInteractorStyle.

void vtkContextInteractorStyle::SetScene ( vtkContextScene * scene )

Set the scene to forward user events to. Refresh the view when the scene is dirty and no event is being processed. The scene is observed (vtkCommand::ModifiedEvent) and a refresh on the view is called appropriately: scene is dirty and no event is being processed.

vtkContextScene* vtkContextInteractorStyle::GetScene ( )

Return the observed scene.

virtual void vtkContextInteractorStyle::OnSceneModified ( )

virtual

Called when the scene is modified. Refresh the scene if needed.

virtual void vtkContextInteractorStyle::OnMouseMove ( )

virtual

Called when the user moves the mouse Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnLeftButtonDown ( )

virtual

Called when the user clicks the mouse left button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnLeftButtonUp ( )

virtual

Called when the user releases the mouse left button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnMiddleButtonDown ( )

virtual

Called when the user clicks the mouse middle button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnMiddleButtonUp ( )

virtual

Called when the user releases the mouse middle button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnRightButtonDown ( )

virtual

Called when the user clicks the mouse right button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnRightButtonUp ( )

virtual

Called when the user releases the mouse right button. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnMouseWheelForward ( )

virtual

Called when the user moves the mouse wheel forward. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnMouseWheelBackward ( )

virtual

Called when the user moves the mouse wheel backward. Default behavior forwards the event to the observed scene.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnSelection ( unsigned int rect[5] )

virtual

Place holder for future implementation. Default behavior forwards the event to the observed scene.

virtual void vtkContextInteractorStyle::OnChar ( )

virtual

Handle key presses.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnKeyPress ( )

virtual

Called when the user presses a key.

Reimplemented from vtkInteractorStyle.

virtual void vtkContextInteractorStyle::OnKeyRelease ( )

virtual

Called when the user releases a key.

void vtkContextInteractorStyle::BeginProcessingEvent ( )

protected

Inform the interactor style that an event is being processed. That way is knows to not refresh the view (the view will eventually be refreshed at the end.

void vtkContextInteractorStyle::EndProcessingEvent ( )

protected

Inform the interactor style that an event is finished to be processed. If no other event is being processed it check if the scene needs to be rendered (scene is dirty)
