Member Function Documentation

VTKViewer_RenderWindowInteractor * VTKViewer_RenderWindowInteractor::New ( ) [static]

Create new instance of VTKViewer_RenderWindowInteractor

References TestSalomeApp.ret, and VTKViewer_RenderWindowInteractor().

VTKViewer_RenderWindowInteractor.vtkTypeMacro	(	VTKViewer_RenderWindowInteractor	,
		vtkRenderWindowInteractor
	)

void VTKViewer_RenderWindowInteractor::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

Print interactor to stream

Parameters:

os	- stream
indent

void VTKViewer_RenderWindowInteractor::Initialize ( ) [virtual]

Description:
Initializes the event handlers without an XtAppContext. This is
good for when you don`t have a user interface, but you still
want to have mouse interaction.
We never allow the VTKViewer_RenderWindowInteractor to control
the event loop. The application always has the control.

References Enable(), myBasicPicker, and SetSelectionTolerance().

void VTKViewer_RenderWindowInteractor::SetInteractorStyle ( vtkInteractorObserver * theInteractor ) [virtual]

Sets interactor style.

References myInteractorStyle.

VTKViewer_InteractorStyle* VTKViewer_RenderWindowInteractor.GetInteractorStyle ( ) const

Return interactor style pointer.

void VTKViewer_RenderWindowInteractor::Start ( ) [virtual]

Description:
This will start up the X event loop and never return. If you
call this method it will loop processing X events until the
application is exited.

void VTKViewer_RenderWindowInteractor::Enable ( ) [virtual]

Description:
Enable/Disable interactions. By default interactors are enabled when
initialized. Initialize() must be called prior to enabling/disabling
interaction. These methods are used when a window/widget is being
shared by multiple renderers and interactors. This allows a "modal"
display where one interactor is active when its data is to be displayed
and all other interactors associated with the widget are disabled
when their data is not displayed.

void VTKViewer_RenderWindowInteractor::Disable ( ) [virtual]

See Enable().

void VTKViewer_RenderWindowInteractor::UpdateSize	(	int	w,
		int	h
	)		`[virtual]`

Description:
Event loop notification member for Window size change

int VTKViewer_RenderWindowInteractor::CreateTimer ( int ) [virtual]

Starts the QTimer instance on defined microseconds

Description: Timer methods must be overridden by platform dependent subclasses. flag is passed to indicate if this is first timer set or an update as Win32 uses repeating timers, whereas X uses One shot more timer if flag == VTKXI_TIMER_FIRST Win32 and X should createtimer otherwise Win32 should exit and X should perform AddTimeOut

Return values:

1

Start a one-shot timer for 10ms.

int VTKViewer_RenderWindowInteractor::DestroyTimer ( void ) [virtual]

See also:: CreateTimer(int )

Return values:

1

QTimer will automatically expire after 10ms. So we do not need to do anything here. In fact, we should not even Stop() the QTimer here because doing this will skip some of the processing that the TimerFunc() does and will result in undesirable effects. For example, this will result in vtkLODActor to leave the models in low-res mode after the mouse stops moving.

virtual void VTKViewer_RenderWindowInteractor.TerminateApp ( void ) [virtual]

Description:
This function is called on 'q','e' keypress if exitmethod is not
specified and should be overidden by platform dependent subclasses
to provide a termination procedure if one is required.

Not all of these slots are needed in VTK_MAJOR_VERSION=3,
but moc does not understand "#if VTK_MAJOR_VERSION". Hence,
we have to include all of these for the time being. Once,
this bug in MOC is fixed, we can separate these.
