Detailed Description

A list of records to allow configurable sorting and more.

Todo: improve API

Definition at line 45 of file KDbTableViewData.h.

Constructor & Destructor Documentation

◆ KDbTableViewData() [1/4]

KDbTableViewData::KDbTableViewData ( )

Non-db-aware version.

Definition at line 307 of file KDbTableViewData.cpp.

◆ KDbTableViewData() [2/4]

KDbTableViewData::KDbTableViewData ( KDbCursor * c )

explicit

Db-aware version. The cursor is not owned by the data.

Definition at line 317 of file KDbTableViewData.cpp.

◆ KDbTableViewData() [3/4]

KDbTableViewData::KDbTableViewData	(	const QList< QVariant > &	keys,
		const QList< QVariant > &	values,
		KDbField::Type	keyType = KDbField::Text,
		KDbField::Type	valueType = KDbField::Text )

Defines two-column table usually used with comboboxes. First column is invisible and contains key values. Second column and contains user-visible value.

Parameters

keys	a list of keys
values	a list of text values (must be of the same length as keys list)
keyType	a type for keys
valueType	a type for values

Todo: make this more generic: allow to add more columns!

Definition at line 353 of file KDbTableViewData.cpp.

◆ KDbTableViewData() [4/4]

KDbTableViewData::KDbTableViewData	(	KDbField::Type	keyType,
		KDbField::Type	valueType )

Like above constructor, but keys and values are not provided. You can do this later by calling append(KDbRecordData*) method. (KDbRecordData object must have exactly two columns)

Definition at line 380 of file KDbTableViewData.cpp.

◆ ~KDbTableViewData()

KDbTableViewData::~KDbTableViewData ( )

override

Definition at line 385 of file KDbTableViewData.cpp.

◆ aboutToDeleteRecord

void KDbTableViewData::aboutToDeleteRecord	(	KDbRecordData *	record,
		KDbResultInfo *	result,
		bool	repaint )

signal

Emitted before deleting of a current record. Connect this signal to your slot and set result->success to false to disallow this deleting.

◆ aboutToInsertRecord

void KDbTableViewData::aboutToInsertRecord	(	KDbRecordData *	record,
		KDbResultInfo *	result,
		bool	repaint )

signal

Emitted before inserting of a new, current record. Connect this signal to your slot and set result->success to false to disallow this inserting. You can also change columns in record.

◆ aboutToUpdateRecord

void KDbTableViewData::aboutToUpdateRecord	(	KDbRecordData *	record,
		KDbRecordEditBuffer *	buffer,
		KDbResultInfo *	result )

signal

Emitted before changing of an edited, current record. Connect this signal to your slot and set result->success to false to disallow this change. You can also change columns in record.

◆ addColumn()

void KDbTableViewData::addColumn ( KDbTableViewColumn * col )

Adds column col. Warning: col will be owned by this object, and deleted on its destruction.

Definition at line 399 of file KDbTableViewData.cpp.

◆ append()

void KDbTableViewData::append ( KDbRecordData * record )

inline

Definition at line 257 of file KDbTableViewData.h.

◆ at()

KDbRecordData * KDbTableViewData::at ( int index )

inline

Definition at line 233 of file KDbTableViewData.h.

◆ autoIncrementedColumn()

int KDbTableViewData::autoIncrementedColumn ( ) const

Todo: add this as well? void insertRecord(KDbRecordData *record, KDbRecordData *aboveRecord)

Returns: index of autoincremented column. The result is cached.

Todo

what about multiple autoinc columns?

what about changing column order?

Definition at line 877 of file KDbTableViewData.cpp.

◆ begin()

KDbTableViewDataIterator KDbTableViewData::begin ( )

inline

Definition at line 269 of file KDbTableViewData.h.

◆ clearInternal()

void KDbTableViewData::clearInternal ( bool processEvents = true )

virtual

method, used mostly by specialized classes like KexiTableView. Clears internal record structures. Record-edit buffer is cleared. Does not touch data @ database backend. Use deleteAllRecords() to safely delete all records.

Todo: this is time consuming: find better data model

Definition at line 845 of file KDbTableViewData.cpp.

◆ clearRecordEditBuffer()

void KDbTableViewData::clearRecordEditBuffer ( )

Clears and initializes internal record edit buffer for incoming editing. Creates buffer using recordEditBuffer(false) (false means not db-aware type) if our data is not db-aware, or db-aware buffer if data is db-aware (isDBAware()==true).

See also: KDbRecordEditBuffer

Definition at line 585 of file KDbTableViewData.cpp.

◆ column()

KDbTableViewColumn * KDbTableViewData::column ( int c )

Returns: column at index index (visible or not)

Definition at line 475 of file KDbTableViewData.cpp.

◆ columnCount()

int KDbTableViewData::columnCount ( ) const

Definition at line 455 of file KDbTableViewData.cpp.

inline

Definition at line 263 of file KDbTableViewData.h.

◆ constEnd()

KDbTableViewDataConstIterator KDbTableViewData::constEnd ( ) const

inline

Definition at line 266 of file KDbTableViewData.h.

◆ containsRecordIdInfo()

bool KDbTableViewData::containsRecordIdInfo ( ) const

Returns: true if ROWID information is stored within every record. Only reasonable for db-aware version. ROWID information is available if KDbDriverBehavior::ROW_ID_FIELD_RETURNS_LAST_AUTOINCREMENTED_VALUE == false for a KDb database driver and a table has no primary key defined. Phisically, ROWID information is stored after last KDbRecordData's element, so every KDbRecordData's length is expanded by one.

Definition at line 510 of file KDbTableViewData.cpp.

◆ count()

virtual int KDbTableViewData::count ( ) const

inlinevirtual

Definition at line 236 of file KDbTableViewData.h.

Definition at line 490 of file KDbTableViewData.cpp.

◆ dbTableName()

QString KDbTableViewData::dbTableName ( ) const

For db-aware data set only: table name is returned; equivalent to cursor()->query()->parentTable()->name().

Definition at line 520 of file KDbTableViewData.cpp.

◆ deleteAllRecords()

bool KDbTableViewData::deleteAllRecords ( bool repaint = false )

virtual

Deletes all records. Works either for db-aware and non db-aware tables. Column's definition is not changed. For db-aware version, all records are removed from a database. Record-edit buffer is cleared.

If repaint is true, reloadRequested() signal is emitted after deleting (if at least one record was deleted), so presenters can repaint their contents.

Returns: true on success.

Definition at line 862 of file KDbTableViewData.cpp.

◆ deleteLater

void KDbTableViewData::deleteLater ( )

slot

Clean up.

Definition at line 393 of file KDbTableViewData.cpp.

◆ deleteRecord()

bool KDbTableViewData::deleteRecord	(	KDbRecordData *	record,

void KDbTableViewData::removeLast ( )

inline

Definition at line 254 of file KDbTableViewData.h.

◆ result()

const KDbResultInfo & KDbTableViewData::result ( ) const

Returns: last operation's result information (always not null).

Definition at line 505 of file KDbTableViewData.cpp.

◆ saveNewRecord()

bool KDbTableViewData::saveNewRecord	(	KDbRecordData *	record,
		bool	repaint = false )

Definition at line 776 of file KDbTableViewData.cpp.

◆ saveRecordChanges()

bool KDbTableViewData::saveRecordChanges	(	KDbRecordData *	record,
		bool	repaint = false )

Definition at line 762 of file KDbTableViewData.cpp.

◆ setInsertingEnabled()

void KDbTableViewData::setInsertingEnabled ( bool set )

virtual

Sets insertingEnabled flag. If true, empty record is available If set is true, read-only flag will be cleared automatically.

See also: setReadOnly()

Definition at line 576 of file KDbTableViewData.cpp.

◆ setReadOnly()

void KDbTableViewData::setReadOnly ( bool set )

virtual

Sets readOnly flag for this data. If set is true, insertingEnabled flag will be cleared automatically.

See also: isInsertingEnabled()

Definition at line 567 of file KDbTableViewData.cpp.

◆ setSorting()

void KDbTableViewData::setSorting	(	int	column,
		KDbOrderByColumn::SortOrder	order = KDbOrderByColumn::SortOrder::Ascending )

Sets sorting for column. If column is -1, sorting is disabled.

Definition at line 527 of file KDbTableViewData.cpp.

◆ sort()

void KDbTableViewData::sort ( )

Sorts this data using previously set order.

Definition at line 559 of file KDbTableViewData.cpp.

◆ sortColumn()

int KDbTableViewData::sortColumn ( ) const

Returns: the column number by which the data is sorted, or -1 if sorting is disabled. Initial sorted column number for data after instantiating object is -1.

Definition at line 549 of file KDbTableViewData.cpp.

◆ sortOrder()

KDbOrderByColumn::SortOrder KDbTableViewData::sortOrder ( ) const

Returns: sorting order. This is independent of whether the data is actually sorted. sortColumn() should be checked first to see if sorting for any column is enabled (by default it is not).

Definition at line 554 of file KDbTableViewData.cpp.

◆ updateRecordEditBuffer() [1/2]

bool KDbTableViewData::updateRecordEditBuffer	(	KDbRecordData *	record,
		int	colnum,
		const QVariant &	newval,
		bool	allowSignals = true )

Added for convenience. Like above but it's assumed that record record's columns are ordered like in table view, not like in form view. Don't use this with form views.

Definition at line 649 of file KDbTableViewData.cpp.

◆ updateRecordEditBuffer() [2/2]

bool KDbTableViewData::updateRecordEditBuffer	(	KDbRecordData *	record,
		int	colnum,
		KDbTableViewColumn *	col,
		const QVariant &	newval,
		bool	allowSignals = true )

Added for convenience. Like above but newval is passed by value.

Definition at line 641 of file KDbTableViewData.cpp.

◆ updateRecordEditBufferRef()

bool KDbTableViewData::updateRecordEditBufferRef	(	KDbRecordData *	record,
		int	colnum,
		KDbTableViewColumn *	col,
		QVariant *	newval,
		bool	allowSignals = true,
		QVariant *	visibleValueForLookupField = nullptr )

Updates internal record edit buffer: currently edited column col (number colnum) has now assigned new value of newval. Uses column's caption to address the column in buffer if the buffer is of simple type, or db-aware buffer if (isDBAware()==true). (then fields are addressed with KDbField, instead of caption strings). If allowSignals is true (the default), aboutToChangeCell() signal is emitted. visibleValueForLookupField allows to pass visible value (usually a text) for a lookup field (only reasonable if col->visibleLookupColumnInfo != 0). Note that newval may be changed in aboutToChangeCell() signal handler. If either record or col or newval is nullptr, false is returned.

◆ visibleColumn()

KDbTableViewColumn * KDbTableViewData::visibleColumn ( int index )

Returns: visible column at index index

Definition at line 480 of file KDbTableViewData.cpp.

◆ visibleColumnCount()

int KDbTableViewData::visibleColumnCount ( ) const

Returns: number of visible columns

Definition at line 460 of file KDbTableViewData.cpp.

◆ visibleColumnIndex()

int KDbTableViewData::visibleColumnIndex ( int globalIndex ) const

Returns: Index on list of visible columns for column globalIndex or -1 if column at globalIndex is not visible.

Definition at line 450 of file KDbTableViewData.cpp.

◆ visibleColumns()

QList< KDbTableViewColumn * > * KDbTableViewData::visibleColumns ( )

Returns: list of visible columns
