Constructor & Destructor Documentation

ProtoNode()

ProtoNode::ProtoNode ( proto_node * node = NULL, ProtoNode * parent = nullptr )

explicit

Constructs a new ProtoNode instance.

Parameters

node	The underlying core proto_node, defaults to NULL.
parent	The parent ProtoNode, defaults to nullptr.

Member Function Documentation

child()

ProtoNode * ProtoNode::child

(

int

row

)

const

Retrieves a specific child node by its row index.

Parameters

row	The index of the child node to retrieve.

Returns

A pointer to the child ProtoNode.

children()

ProtoNode::ChildIterator ProtoNode::children

(

)

const

Retrieves a child iterator for traversing this node's children.

Returns

A ChildIterator positioned at the first child.

childrenCount()

int ProtoNode::childrenCount

(

)

const

Retrieves the total number of child nodes.

Returns

The child count.

fieldInfo()

field_info * ProtoNode::fieldInfo

(

)

const

Retrieves the field information of the underlying node.

Returns

The node's field_info, or nullptr if the node is invalid or has none.

hfId()

int ProtoNode::hfId

(

)

const

Retrieves the header field id of the underlying node.

Returns

The node's header field id, or -1 if the node has no header field.

isChild()

bool ProtoNode::isChild

(

)

const

Checks if this node is a child of another node.

Returns

True if it is a child node, false otherwise.

isExpanded()

bool ProtoNode::isExpanded

(

)

const

Checks if the node is expanded in the view.

Returns

True if expanded, false otherwise.

isValid()

bool ProtoNode::isValid

(

)

const

Checks if the protocol node is valid.

Returns

True if the underlying node is valid, false otherwise.

labelText()

QString ProtoNode::labelText

(

)

const

Retrieves the display label text for this node.

Returns

The label text string.

parentNode()

ProtoNode * ProtoNode::parentNode

(

)

const

Retrieves the parent node of this node.

Returns

A pointer to the parent ProtoNode.

protoNode()

proto_node * ProtoNode::protoNode

(

)

const

Retrieves the underlying core proto_node structure.

Returns

A pointer to the proto_node.

row()

int ProtoNode::row

(

)

const

Retrieves the row index of this node relative to its parent.

Returns

The row index.
