21.4.6.4 chMax

This element is used to indicate when to enable and disable the user interface components associated with adding a new shape to a diagram. This element defines a max number of nodes a diagram can support through the user interface directly.

[Example:

Consider the following example of chMax usage in DiagramML:

<varLst>
  <chMax val="5"/>
  <dir val="norm"/>
  <resizeHandles val="exact" />
</varLst>

In this example we define the user interface to only be enabled to insert five nodes. end example]

Attributes

val (Maximum Children Value)

This attribute indicates the maximum number of children the node can have before the user interface should be disabled. A value of -1 indicates an infinite number of children. Default value is -1.

The possible values for this attribute are defined by the ST_NodeCount simple type (21.4.7.44).
