Using SMILE > Anatomy of a node > Other node attributes

Node attributes that not related to inference are grouped in the DSL_nodeInfo object, accessible through DSL_node::Info method. In turn, the DSL_nodeInfo provides access to the following objects:

•header: textual attributes, like node identifier, name, and description, through DSL_nodeInfo::Header method returning a reference to DSL_header object. For convenience, these attributes are also available directly through DSL_node member functions, like DSL_node::GetName.

•screen information: position, colors, border thickness, etc., through DSL_nodeInfo::Screen method returning a reference to DSL_screenInfo object.

•user properties: a list of key/value pairs used for application-specific purposes, through DSL_nodeInfo::UserProperties method returning a reference to DSL_userProperties object.

The example below displays a node's screen position and size:

int nodeHandle = …;

DSL_node *node = net.GetNode(nodeHandle);

DSL_nodeInfo &info = node->Info();

const DSL_rectangle &pos = info.Screen().position;

printf("Node center: (%d, %d), size: (%d,%d)\n",

pos.center_X, pos.center_Y,

pos.width, pos.height);
