Detailed Description

This class implements table model for manipulating a task.

Constructor & Destructor Documentation

CTSPModel::CTSPModel ( QObject * parent = 0 )

Class constructor.

Parameters

parent The parent of the table model.

Member Function Documentation

void CTSPModel::clear ( )

Resets the table, setting all its elements to 0.

See also: randomize()

Here is the call graph for this function:

int CTSPModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

Returns the column count in the table.

Returns: Number of columns in the table.

Actually, this function returns the number of cities in the current task.

See also: numCities(), rowCount()

QVariant CTSPModel::data	(	const QModelIndex &	index,
		int	role = `Qt::DisplayRole`
	)		const

Returns the data stored under the given role for the item referred to by the index.

Parameters

index	An item index to get data from.
role	The role to get data for.

Returns: Corresponding data.

See also: setData(), headerData()

Hack:: HACK: Converting to string to prevent spinbox in edit mode

Here is the call graph for this function:

Qt::ItemFlags CTSPModel::flags ( const QModelIndex & index ) const

virtual

Returns the item flags for the given index.

Parameters

index An item index to get flags from.

Returns: Corresponding item flags.

Reimplemented from QAbstractItemModel.

Here is the call graph for this function:

QVariant CTSPModel::headerData	(	int	section,
		Qt::Orientation	orientation,
		int	role = `Qt::DisplayRole`
	)		const

virtual

Returns the data for the given role and section in the header with the specified orientation.

Parameters

section	The section to get header data for.
orientation	The orientation to get header data for.
role	The role to get header data for.

Returns: Corresponding header data.

For horizontal headers, the section number corresponds to the column number of items shown beneath it. For vertical headers, the section number typically to the row number of items shown alongside it.

Reimplemented from QAbstractItemModel.
