Detailed Description

An item representing a single vertex in the graph model.

In QT speak a single vertex represents a single row in the matrix of the data model.

The model can hold either a general graph vertices or tree vertices, all depending on how the model is instantiated. If in "tree mode" a vertex has a parent (and possibly children). See individual method documentation for tree or non-tree usage.

Member Enumeration Documentation

enum GraphModelItem::column_index

These are the "columns" of the data item (row). These are the fields that we currently expose to the GUI via the data model. Any GUI element can request these fields and retrieve the data back.

Member Function Documentation

bool GraphModelItem::circular

(

)

const

Retrieve whether this node has been seen before in the tree or in the graph.

void GraphModelItem::set_circular

(

bool

circular

)

In our model the circular property is set whenever we have seen this node before.

void GraphModelItem::set_mem_type

(

std::string

type

)

If this item represents a dependency, used to set dependency type.

Parameters

type	the type of dependency this item represents (Dependency::DependencyType enum value)
