Detailed Description

This class represents the table object in the Processes tab of main window.

Constructor & Destructor Documentation

TableModel::TableModel

(

QObject *

parent = 0

)

Constructor. Initializes a ProcessExtractor type object, populates a list by function calls to select rows from database. Raises signal every 3 seconds to call refreshTable() so that list of running processing is refrehed in the database and hence the table.

TableModel::TableModel	(	QList< Process >	pairs,
		QObject *	parent = 0
	)

Contructor to assign data member listOfProcesses with

Parameters:

pairs

TableModel::~TableModel

Member Function Documentation

int TableModel::columnCount

(

const QModelIndex &

parent

)

const

Returns the number of columns in database and table

QVariant TableModel::data	(	const QModelIndex &	index,
		int	role
	)			const

Depending on the

Parameters:

index

passed, function returns appropriate value in corresponding row-column pair

Qt::ItemFlags TableModel::flags

(

const QModelIndex &

index

)

const

Function to set flag values

QList< Process > TableModel::getList

(

)

QVariant TableModel::headerData	(	int	section,
		Qt::Orientation	orientation,
		int	role
	)			const

Function to assign header information on the table

bool TableModel::insertRows	(	int	position,
		int	rows,
		const QModelIndex &	index = QModelIndex()
	)

Function to insert empty rows into the table

bool TableModel::refillRows

(

const QModelIndex &

index = QModelIndex()

)

Function called when timer signal raised. Refrehes database and table rows with afresh with latest process information

void TableModel::refreshTable

(

)

[private, slot]

Slot being called when timer signal is raised.

bool TableModel::removeRows	(	int	position,
		int	rows,
		const QModelIndex &	index = QModelIndex()
	)

Function to remove

Parameters:

	rows	number of rows from given
	position

int TableModel::rowCount

(

const QModelIndex &

parent

)

const

Returns the size of listOfProcesses

void TableModel::rowSelected

(

QModelIndex

index

)

[private, slot]

This is a slot raised by signal of row being double clicked in a table. It initiates the pop up window displaying all files used by the selected process.

bool TableModel::setData	(	const QModelIndex &	index,
		const QVariant &	value,
		int	role = Qt::EditRole
	)
