Detailed Description

Qt model storing a tabel in dictionaries.

Member Function Documentation

add()

def core.util.models.DictTableModel.add	(		self,
			key,
			data
	)

Append key and data to dictionary, update model.

Parameters

key	dict key
data	dict data

Returns

key: dict key

columnCount()

def core.util.models.DictTableModel.columnCount	(		self,
			parent = QtCore.QModelIndex()
	)

Gives the number of data fields.

Returns

int: number of data fields

data()

def core.util.models.DictTableModel.data	(		self,
			index,
			role
	)

Get data from model for a given cell.

Data can have a role that affects display.

     @param QModelIndex index: cell for which data is requested
     @param ItemDataRole role: role for which data is requested

     @return QVariant: data for given cell and role

flags()

def core.util.models.DictTableModel.flags	(		self,
			index
	)

Determines what can be done with entry cells in the table view.

Parameters

QModelIndex

index: cell fo which the flags are requested

Returns

Qt.ItemFlags: actins allowed fotr this cell

getKeyByNumber()

def core.util.models.DictTableModel.getKeyByNumber	(		self,
			n
	)

Get a dict key by index number.

Parameters

n	int: index number for element

Returns

key: key at index

getNumberByKey()

def core.util.models.DictTableModel.getNumberByKey	(		self,
			key
	)

Get index number for dict key.

Parameters

key

dict key

Returns

int: index numer for key

Warning

index number for a key changes when keys with lower numbers are removed.

headerData()

def core.util.models.DictTableModel.headerData	(		self,
			section,
			orientation,
			role = QtCore.Qt.DisplayRole
	)

Data for the table view headers.

Parameters

int	section: number of the column to get header data for
Qt.Orientation	orientation of header (horizontal or vertical)
ItemDataRole	role for which to get data

Returns

QVariant: header data for given column and role

pop()

def core.util.models.DictTableModel.pop	(		self,
			key
	)

Remove key from dictionary.

Parameters

key	dict key to remove

Returns

value: value removed from dict

rowCount()

def core.util.models.DictTableModel.rowCount	(		self,
			parent = QtCore.QModelIndex()
	)

Gives the number of stored items.

Returns

int: number of items
