`vtkmodules.tk.vtkTkRenderWidget`#

A simple vtkTkRenderWidget for tkinter.

Created by David Gobbi, April 1999

May ??, 1999 - Modifications performed by Heather Drury, to rewrite _pan to match method in TkInteractor.tcl May 11, 1999 - Major rewrite by David Gobbi to make the interactor bindings identical to the TkInteractor.tcl bindings. July 14, 1999 - Added modification by Ken Martin for VTK 2.4, to use vtk widgets instead of Togl. Aug 29, 1999 - Renamed file to vtkRenderWidget.py Nov 14, 1999 - Added support for keyword ‘rw’ Mar 23, 2000 - Extensive but backwards compatible changes, improved documentation

A few important notes:

This class is meant to be used as a base-class widget for doing VTK rendering in Python.

In VTK (and C++) there is a very important distinction between public ivars (attributes in pythonspeak), protected ivars, and private ivars. When you write a python class that you want to ‘look and feel’ like a VTK class, you should follow these rules.

Attributes should never be public. Attributes should always be either protected (prefixed with a single underscore) or private (prefixed with a double underscore). You can provide access to attributes through public Set/Get methods (same as VTK).
Use a single underscore to denote a protected attribute, e.g. self._RenderWindow is protected (can be accessed from this class or a derived class).
Use a double underscore to denote a private attribute, e.g. self.__InExpose cannot be accessed outside of this class.

All attributes should be ‘declared’ in the init() function i.e. set to some initial value. Don’t forget that ‘None’ means ‘NULL’ - the python/vtk wrappers guarantee their equivalence.

class vtkmodules.tk.vtkTkRenderWidget.vtkTkRenderWidget(master, cnf={}, **kw)#

Bases: tkinter.Widget

A vtkTkRenderWidget for Python.

Use GetRenderWindow() to get the vtkRenderWindow.

Create with the keyword stereo=1 in order to generate a stereo-capable window.

Create with the keyword focus_on_enter=1 to enable focus-follows-mouse. The default is for a click-to-focus mode.

Initialization

Constructor.

Keyword arguments:

rw – Use passed render window instead of creating a new one.

stereo – If True, generate a stereo-capable window. Defaults to False.

focus_on_enter – If True, use a focus-follows-mouse mode. Defaults to False where the widget will use a click-to-focus mode.
