58 This abstract base class provides a C++ wrapper around the GLwMDraw
59 widget. It allows OpenGL rendering to be performed within a motif wid‐
60 get and is used by the SoXtRenderArea. SoXtGlWidget uses a form widget
61 around two separate GLwMDraw widgets (one for single and one for double
62 buffering), with routines to return the appropriate windows.
63 Subclasses only need to redefine the redraw() routine for rendering and
65 processEvent() routine if they are interested in receiving X events.
66
68 void setBorder(SbBool onOrOff)
69 SbBool isBorder() const
70 Show and hide the border around the glx widgets (thickness 3).
71 Default is no border (FALSE). (The SoXtRenderArea subclass defaults
72 turns the border on by default.)
73 virtual void setDoubleBuffer(SbBool onOrOff)
75 SbBool isDoubleBuffer()
76 Routine which dynamically changes between single and double buffer‐
77 ing. Default is double buffer off. (The SoXtRenderArea subclass
78 makes it double buffer by default.)
79 Window getNormalWindow()
81 Window getOverlayWindow()
82 GLXContext getNormalContext()
83 GLXContext getOverlayContext()
84 Widget getNormalWidget()
85 Widget getOverlayWidget()
86 Get the current normal and overlay GLX windows, contexes and wid‐
87 gets, which are needed as arguments to glXMakeCurrent() when doing
88 drawing in the normal or overlay planes.
89 Note: These should not be cached by users because they will change
91 as single/double buffering changes.
92 virtual void setNormalVisual(XVisualInfo *vis)
94 XVisualInfo * getNormalVisual()
95 virtual void setOverlayVisual(XVisualInfo *vis)
96 XVisualInfo * getOverlayVisual()
97 Specify exactly what the visual should be for the normal and overlay
98 window. This allows the user to create all possible visuals sup‐
99 ported by OpenGL. The XVisualInfo structure should be a valid OpenGL
100 visual returned by glXChooseVisual(). This structure will be copied
101 by the SoXtGLWidget; the application is responsible for freeing the
102 visual info with XFree() when done. (The methods for setting the
103 visual are virtual so that derived classes can know when the visual
104 is changing.)
105 void setDrawToFrontBufferEnable(SbBool enableFlag)
107 SbBool isDrawToFrontBufferEnable() const
108 Inventor 2.1 changed the behavior of double buffered windows to
109 redraw temporary to the front buffer when an expose event is
110 received or when a new sceneGraph() is set on an SoXtRenderArea.
111 This does not apply for general interactive rendering. The idea is
112 that it is better to see something redraw (especially if it is slow)
113 than to see garbage in the window (in the expose case) or an old
114 invalid scene graph (in the SoXtRenderArea::setSceneGraph() case).
115 This API enables you to turn this functionality OFF if for some rea‐
117 son you are unable to prevent repeated expose from causing a redraw
118 (which is bad and should be fixed, as it gets worse for large
119 scenes). This will be the case for example if you can't create a
120 pulldown menu in the popup planes.
121 NOTE: this api might be removed in some future releases and is only
123 intended as a porting help for Inventor 2.0 to 2.1
