[ISO/IEC 29500-1 1st Edition] cNvSpPr (Non-Visual Drawing Properties for a Shape)

This element specifies the non-visual drawing properties for a shape. These properties are to be used by the generating application to determine how the shape should be dealt with

[Example: Consider the shape that has a shape lock applied to it.

    <p:cNvPr id="2" name="Rectangle 1"/>
      <a:spLocks noGrp="1"/>

This shape lock is stored within the non-visual drawing properties for this shape. end example]

txBox (Text Box)

Namespace: .../drawingml/2006/main

Specifies that the corresponding shape is a text box and thus should be treated as such by the generating application. If this attribute is omitted then it is assumed that the corresponding shape is not specifically a text box.

[Note: Because a shape is not specified to be a text box does not mean that it cannot have text attached to it. A text box is merely a specialized shape with specific properties. end note]

The possible values for this attribute are defined by the W3C XML Schema boolean datatype.

[Note: The W3C XML Schema definition of this element’s content model (CT_NonVisualDrawingShapeProps) is located in §A.4.1. end note]
