Detailed Description

TuiNode objects are linked together in a network of nodes to form the structure of a menu which may be navigated using the cursor keys.

Each node has a single line of text which will be displayed when a node is active. Depending on the sub-class for a particular node, it may be used to edit data of one sort of another.

Constructor & Destructor Documentation

TuiNode::TuiNode	(	const QString &	text,
		TuiNode *	parent = NULL,
		TuiNode *	prev = NULL
	)

Create a TuiNode.

Parameters

text	the text to display for this node
parent	the node for the parent menu item
prev	the previous node in the current menu (typically shares the same parent)

Member Function Documentation

virtual void TuiNode::loopToTheLast ( )

virtual

Set prevNode to the last of the chain of nextNode-s.

Call for the first node of a menu after all others have been added.

void TuiNode::updateNodeNumber ( )

protected

Updates nodeNumber, ancestorNumbers and prefixText.

Member Data Documentation

QList<int> TuiNode::ancestorsNumbers

protected

Contains the numbers of the parent nodes in the hierarchy.

The last element is the number of the node in the current menu.

Definition at line 83 of file TuiNode.hpp.

int TuiNode::nodeNumber

protected

Number of the node in the current menu.

Automatically set to 1 if there is no prevNode.

Definition at line 80 of file TuiNode.hpp.

QString TuiNode::prefixText

protected

Text of the prefix containing the hierarchical node number.

Definition at line 76 of file TuiNode.hpp.
