Detailed Description

A item-based model for storing accounting results.

A result in a FdItemResults instance.

Remarks: When changing the number of columns, it is necessary to update #ResultsColumn enum, headerData(), data() and setData().

Constructor & Destructor Documentation

FdModelResults::FdModelResults ( FdSubWindow * parent )

explicit

Definition at line 28 of file FdModelResults.cpp.

FdModelResults::FdModelResults	(	FdSubWindow *	parent,
		QDomElement &	results
	)

Constructor to create an instance from data file.

Definition at line 36 of file FdModelResults.cpp.

FdModelResults::FdModelResults	(	FdSubWindow *	parent,
		const FdModelResults *	model
	)

Copy constructor to build an instance based on model.

This is no exact copy, it is used to create a new year accounting.

Definition at line 54 of file FdModelResults.cpp.

Member Function Documentation

QModelIndex FdModelResults::addCalculation ( const QModelIndex & selected )

slot

Add a new calculation just after selected or at the end of the table if there is no selection.

Definition at line 501 of file FdModelResults.cpp.

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

Definition at line 264 of file FdModelResults.cpp.

QVariant FdModelResults::data	(	const FdItemResults_p	calculation,
		ResultsColumn	column
	)		const

Definition at line 70 of file FdModelResults.cpp.

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

Definition at line 87 of file FdModelResults.cpp.

bool FdModelResults::dropMimeData	(	const QMimeData *	data,
		Qt::DropAction	action,
		int	row,
		int	column,
		const QModelIndex &	parent
	)

Handles items drop. This action is undoable, see FdCoaDragDrop.

Definition at line 222 of file FdModelResults.cpp.

QModelIndexList FdModelResults::entryByPartialText ( QString text ) const

This function returns the index of the first entry whose label contains text, or an invalid index if it founds nothing.

Definition at line 350 of file FdModelResults.cpp.

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

Definition at line 175 of file FdModelResults.cpp.

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

Definition at line 154 of file FdModelResults.cpp.

bool FdModelResults::idExists ( QString id ) const

Returns true if the id id already exists. It will also check if id already exists in the chart of accounts.

Definition at line 315 of file FdModelResults.cpp.

QStack< QString > FdModelResults::infixToPostfix ( QString expr )

static

Convert a user input infix expression into a postfix expression, so that the expression can then be computed. It returns a QStack of QString, sorted like a postfix string from bottom to top.

Definition at line 556 of file FdModelResults.cpp.

void FdModelResults::init ( )

private

Definition at line 63 of file FdModelResults.cpp.

void FdModelResults::insertCalculation	(	FdItemResults_p	calculation,
		int	row
	)

Definition at line 269 of file FdModelResults.cpp.

void FdModelResults::insertCalculations	(	QList< FdItemResults_p >	calculations,
		int	row
	)

Definition at line 274 of file FdModelResults.cpp.

bool FdModelResults::isValid ( QString calculation ) const

Parses the expression calculation, a user input and returns false if it contains error.

Definition at line 364 of file FdModelResults.cpp.

FdItemResults_p FdModelResults::item ( QString id ) const

Returns the #FdItemResults_p with the given id, which is invalid if id does not exist. Therefore, the validity of the pointer returned by this function should always be tested calling QSharedPointer::isNull().

Definition at line 326 of file FdModelResults.cpp.

FdItemResults_p FdModelResults::item ( int row ) const

Definition at line 337 of file FdModelResults.cpp.

QList< FdItemResults_p > FdModelResults::items ( ) const

Definition at line 342 of file FdModelResults.cpp.

QMimeData * FdModelResults::mimeData ( const QModelIndexList & indexes ) const

This function doesn't serialise the items. It simply stores in a QMimeData the row number of dragged rows.

In this class, drag and drop of items is a simple change of row number. There are no destruction/creation.

Definition at line 203 of file FdModelResults.cpp.

QStringList FdModelResults::mimeTypes ( ) const

Definition at line 193 of file FdModelResults.cpp.

int FdModelResults::opPriority ( QString op )

static

Definition at line 638 of file FdModelResults.cpp.

double FdModelResults::parse ( QString calculation ) const

Parses the expression calculation, a user input.

This function recognizes items id, you just have to put them between quoting marks "<i>id</i>". First, the function will try to match an FdItemCoa, then an FdItemResults. Symbols +, -, *, /, ( and ) can be used to set up calculs. Everything else will be treated as scalars.

Definition at line 415 of file FdModelResults.cpp.

double FdModelResults::parseItem ( QString element ) const

Parses element. If element is an account/category or result id, it returns its value. If element is a scalar, it converts it to double.

Definition at line 454 of file FdModelResults.cpp.

void FdModelResults::recomputeResults ( )

slot

Recomputes all results.

See Also: parse() This function takes care of parsing the user input.

Definition at line 542 of file FdModelResults.cpp.

QAction * FdModelResults::redo ( )

Creates redo action for the tab.

Definition at line 299 of file FdModelResults.cpp.

void FdModelResults::removeCalculation ( FdItemResults_p calculation )

Definition at line 285 of file FdModelResults.cpp.

void FdModelResults::removeCalculations ( QList< FdItemResults_p > calculations )

Definition at line 290 of file FdModelResults.cpp.

bool FdModelResults::removeRows	(	int	row,
		int	count,
		const QModelIndex &	parent = `QModelIndex()`
	)

Definition at line 248 of file FdModelResults.cpp.

void FdModelResults::removeSelected ( const QList< int > & rows )

slot

Removes the selected calculations. This action is undoable (see FdResultsRemove).

Definition at line 531 of file FdModelResults.cpp.

int FdModelResults::rowCount ( const QModelIndex & parent = QModelIndex() ) const

Definition at line 259 of file FdModelResults.cpp.

void FdModelResults::setData	(	FdItemResults_p	calculation,
		ResultsColumn	column,
		const QVariant &	value
	)

Definition at line 101 of file FdModelResults.cpp.

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

Handles user modification of the item fields, calld automatically by the view (FdViewResults).

This function filters user input. It rejects :

Id which is already used.

See Also: parse(), for information on how to complete calculation field.

Definition at line 130 of file FdModelResults.cpp.

Qt::DropActions FdModelResults::supportedDropActions ( ) const

Definition at line 188 of file FdModelResults.cpp.

QDomElement FdModelResults::toXml ( QDomDocument & document ) const

Sets the undostack as cleaned.

Definition at line 481 of file FdModelResults.cpp.

QAction * FdModelResults::undo ( )

Creates undo action for the tab.

Definition at line 307 of file FdModelResults.cpp.
