a simple class to control print indentation
Definition vtkIndent.h:29
platform-independent render window interaction including picking and frame rate control.
an X event driven interface for a RenderWindow
void TerminateApp() override
Break the event loop on 'q','e' keypress.
void UpdateSize(int, int) override
Update the Size data member and set the associated RenderWindow's size.
void Initialize() override
Initializes the event handlers without an XtAppContext.
int InternalDestroyTimer(int platformTimerId) override
X-specific internal timer methods.
void StartEventLoop() override
This will start up the X event loop and never return.
void WaitForEvents()
Wait for new events.
void Finalize()
Deallocate X resource that may have been allocated Also calls finalize on the render window if availa...
int InternalCreateTimer(int timerId, int timerType, unsigned long duration) override
X-specific internal timer methods.
void ProcessEvents() override
Process all user-interaction, timer events and return.
void UpdateSizeNoXResize(int, int)
Update the Size data member and set the associated RenderWindow's size but do not resize the XWindow.
static vtkXRenderWindowInteractor * New()
void DispatchEvent(XEvent *)
~vtkXRenderWindowInteractor() override
void Enable() override
Enable/Disable interactions.
void GetMousePosition(int *x, int *y) override
Re-defines virtual function to get mouse position by querying X-server.
vtkXRenderWindowInteractorInternals * Internal
void Disable() override
Enable/Disable interactions.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
