To create an instance of class vtkWindow, simply invoke its constructor as follows
obj = vtkWindow
obj
is an instance of the vtkWindow class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkWindow = obj.NewInstance ()
vtkWindow = obj.SafeDownCast (vtkObject o)
obj.SetWindowInfo (string )
- These are window system independent methods that are used
to help interface vtkWindow to native windowing systems.
obj.SetParentInfo (string )
- These are window system independent methods that are used
to help interface vtkWindow to native windowing systems.
int = obj.GetPosition ()
- Set/Get the position in screen coordinates of the rendering window.
obj.SetPosition (int , int )
- Set/Get the position in screen coordinates of the rendering window.
obj.SetPosition (int a[2])
- Set/Get the position in screen coordinates of the rendering window.
int = obj.GetSize ()
- Set/Get the size of the window in screen coordinates in pixels.
obj.SetSize (int , int )
- Set/Get the size of the window in screen coordinates in pixels.
obj.SetSize (int a[2])
- Set/Get the size of the window in screen coordinates in pixels.
obj.SetMapped (int )
- Keep track of whether the rendering window has been mapped to screen.
int = obj.GetMapped ()
- Keep track of whether the rendering window has been mapped to screen.
obj.MappedOn ()
- Keep track of whether the rendering window has been mapped to screen.
obj.MappedOff ()
- Keep track of whether the rendering window has been mapped to screen.
obj.SetErase (int )
- Turn on/off erasing the screen between images. This allows multiple
exposure sequences if turned on. You will need to turn double
buffering off or make use of the SwapBuffers methods to prevent
you from swapping buffers between exposures.
int = obj.GetErase ()
- Turn on/off erasing the screen between images. This allows multiple
exposure sequences if turned on. You will need to turn double
buffering off or make use of the SwapBuffers methods to prevent
you from swapping buffers between exposures.
obj.EraseOn ()
- Turn on/off erasing the screen between images. This allows multiple
exposure sequences if turned on. You will need to turn double
buffering off or make use of the SwapBuffers methods to prevent
you from swapping buffers between exposures.
obj.EraseOff ()
- Turn on/off erasing the screen between images. This allows multiple
exposure sequences if turned on. You will need to turn double
buffering off or make use of the SwapBuffers methods to prevent
you from swapping buffers between exposures.
obj.SetDoubleBuffer (int )
- Keep track of whether double buffering is on or off
int = obj.GetDoubleBuffer ()
- Keep track of whether double buffering is on or off
obj.DoubleBufferOn ()
- Keep track of whether double buffering is on or off
obj.DoubleBufferOff ()
- Keep track of whether double buffering is on or off
string = obj.GetWindowName ()
- Get name of rendering window
obj.SetWindowName (string )
- Get name of rendering window
obj.Render ()
- Ask each viewport owned by this Window to render its image and
synchronize this process.
int = obj.GetPixelData (int x, int y, int x2, int y2, int front, vtkUnsignedCharArray data)
- Get the pixel data of an image, transmitted as RGBRGBRGB. The
front argument indicates if the front buffer should be used or the back
buffer. It is the caller's responsibility to delete the resulting
array. It is very important to realize that the memory in this array
is organized from the bottom of the window to the top. The origin
of the screen is in the lower left corner. The y axis increases as
you go up the screen. So the storage of pixels is from left to right
and from bottom to top.
(x,y) is any corner of the rectangle. (x2,y2) is its opposite corner on
the diagonal.
int = obj.GetDPI ()
- Return a best estimate to the dots per inch of the display
device being rendered (or printed).
obj.SetDPI (int )
- Return a best estimate to the dots per inch of the display
device being rendered (or printed).
int = obj.GetDPIMinValue ()
- Return a best estimate to the dots per inch of the display
device being rendered (or printed).
int = obj.GetDPIMaxValue ()
- Return a best estimate to the dots per inch of the display
device being rendered (or printed).
obj.SetOffScreenRendering (int )
- Create a window in memory instead of on the screen. This may not be
supported for every type of window and on some windows you may need to
invoke this prior to the first render.
int = obj.GetOffScreenRendering ()
- Create a window in memory instead of on the screen. This may not be
supported for every type of window and on some windows you may need to
invoke this prior to the first render.
obj.OffScreenRenderingOn ()
- Create a window in memory instead of on the screen. This may not be
supported for every type of window and on some windows you may need to
invoke this prior to the first render.
obj.OffScreenRenderingOff ()
- Create a window in memory instead of on the screen. This may not be
supported for every type of window and on some windows you may need to
invoke this prior to the first render.
obj.MakeCurrent ()
- Make the window current. May be overridden in subclasses to do
for example a glXMakeCurrent or a wglMakeCurrent.
obj.SetTileScale (int , int )
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
obj.SetTileScale (int a[2])
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
int = obj. GetTileScale ()
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
obj.SetTileScale (int s)
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
obj.SetTileViewport (double , double , double , double )
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
obj.SetTileViewport (double a[4])
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
double = obj. GetTileViewport ()
- These methods are used by vtkWindowToImageFilter to tell a VTK window
to simulate a larger window by tiling. For 3D geometry these methods
have no impact. It is just in handling annotation that this information
must be available to the mappers and the coordinate calculations.
