Detailed Description

VSG extension (Preview feature) [Medical] Shape node to display a text box in window coordinates.

This node displays a text box at a fixed location in the viewer window.

The position is specified in normalized device coordinates -1 to 1. Horizontal alignmentH and vertical alignmentV can be specified. For example position -0.98, -0.98, 0 with TOP/LEFT alignment (the default) puts a text box in the upper left corner of the window. The text box automatically expands or shrinks when lines of text are added to or deleted from the box. Positioning a text box in the lower left corner creates a sort of 'console' output overlaying the scene. Note that the alignment options control the positioning of the text box. The text can be left, center or right justified inside the box using the textAlignH field.

In order to have convenient default values for the font properties, by default the font properties are not inherited from the scene graph. By default the text is rendered using an SoText2 node with font name 'Arial:Bold', font size 15 and line spacing 1.1. The application can modify the fontName and fontSize fields or modify text properties directly using the getFontNode() and getTextNode() methods.

Lighting and picking are disabled. A border can be drawn around the box. Text will be rendered on top of whatever is rendered in the main scene graph. The application can modify the text strings directly, but this class also provides some convenience methods that are very useful. For example, the addLine() method appends a new string to the end of the list.

The bounding box of this node is ignored, i.e. it does not contribute to an SoGetBoundingBoxAction traversal and it does not affect a "viewAll" call on the camera or viewer.

Note:
If you are using one of the Open Inventor viewer classes (e.g. SoWinExaminerViewer). You must explicitly create a camera node (e.g. SoPerspectiveCamera) and add it to the scene graph. The viewer will not automatically create a camera, because it will find the camera in this node's internal scene graph.
