Constructor & Destructor Documentation

DtObjectSelector::DtObjectSelector ( )

Default constructor.

virtual DtObjectSelector::~DtObjectSelector ( ) [virtual]

Destructor.

DtObjectSelector::DtObjectSelector ( const DtObjectSelector & orig ) [private]

Copy constructor.

Member Function Documentation

virtual void DtObjectSelector::selectSymbols	(	DtModelDataIter *	iter,
		Qt::KeyboardModifiers	keyState,
		Qt::MouseButtons	mouseState
	)		`[virtual]`

Selects symbols based upon current selector type.

Implements DtSymbolSelector.

static DtObjectSelector* DtObjectSelector::create ( ) [static]

Static creator function.

virtual void DtObjectSelector::setSelectionFilter ( const DtFilter & ) [virtual]

Set filter to filter objects that can be selected.

If filter is NULL, all objects can be selected. Note that when filter is passed in it will be cloned for use by this object. When the filter is set, it also sets selection mode to use that filter

virtual const DtFilter* DtObjectSelector::selectionFilter ( ) const [virtual]

virtual void DtObjectSelector::revalidateSelectedKeys ( DtModelDataIter * iter ) [virtual]

Revalidates current selected keys against the current filter.

virtual void DtObjectSelector::clearFilter ( ) [virtual]

Clears out filter and sets selection mode to normal.

virtual DtSymbol* DtObjectSelector::symbolAtLocation	(	DtModelDataIter *	iter,
		const DtPoint &	pnt
	)		`[virtual]`

Given the database location, return the symbol at the specified location.

Will return the first symbol found

virtual void DtObjectSelector::backupSelectionFilter ( ) [virtual]

Backs-up/restores backed up selection filter.

This is a push/pop mechanism, so, it can be backed up multiple types

virtual bool DtObjectSelector::restoreSelectionFilter ( ) [virtual]

DtObjectSelector& DtObjectSelector::operator= ( const DtObjectSelector & orig ) [private]

Assignment operator.

virtual bool DtObjectSelector::isValidForSelectionMode ( const DtModelData * data ) [protected, virtual]

Returns true if this model data is valid for the specified selection mode.

virtual bool DtObjectSelector::isValidForSelectionMode ( const DtSymbol * symbol ) [protected, virtual]

Returns true if this symbol is valid for the specified selection mode.

virtual bool DtObjectSelector::isValidForMode	(	const DtModelData *	data,
		const DtSymbol *	s
	)		`[protected, virtual]`

Calls either selection mode validators depending on how flags are set.

Can be overridden to provide additional selection functionality

virtual void DtObjectSelector::select	(	DtModelDataIter *	iter,
		QVector< DtModelKey > &	keys,
		Qt::KeyboardModifiers	keyState,
		Qt::MouseButtons	mouseState
	)		`[protected, virtual]`

Selects symbols by using appropriate selection mode.

virtual bool DtObjectSelector::isInRectangle	(	const DtModelData *	data,
		DtSymbol *	s,
		const QPoint &	start,
		const QPoint &	end
	)		const `[protected, virtual]`

Different selection modes.

virtual bool DtObjectSelector::isInPoint	(	const DtModelData *	data,
		DtSymbol *	s,
		const QPoint &	start,
		const QPoint &	end
	)		const `[protected, virtual]`

virtual bool DtObjectSelector::isInCircle	(	const DtModelData *	data,
		DtSymbol *	s,
		const QPoint &	start,
		const QPoint &	end
	)		const `[protected, virtual]`

virtual bool DtObjectSelector::isInRectCircle	(	const DtModelData *	data,
		DtSymbol *	s,
		const QPoint &	start,
		const QPoint &	end
	)		const `[protected, virtual]`

virtual bool DtObjectSelector::selectForMode	(	const DtModelData *	data,
		DtSymbol *	s,
		const QPoint &	start,
		const QPoint &	end
	)		const `[protected, virtual]`

Given the selection mode, sees if the symbol can be selected.

virtual void DtObjectSelector::postProcessForMode	(	DtModelDataIter *	iter,
		const QPoint &	start,
		const QPoint &	end,
		QVector< DtModelKey > &	keys
	)		`[protected, virtual]`

Does any final processing for selection mode.

Currently only works with rect selection mode if rectangle is small (less than 2 pixels on width and height) to find closest selection

virtual void DtObjectSelector::postProcessRectangleMode	(	DtModelDataIter *	iter,
		const QPoint &	start,
		const QPoint &	end,
		QVector< DtModelKey > &	keys
	)		`[protected, virtual]`

virtual void DtObjectSelector::highlightSymbols ( QVector< DtModelKey > * display = NULL ) [protected, virtual]

Highlights all symbols in symbol list.

Implements DtSymbolSelector.

virtual bool DtObjectSelector::passesFinalSelectionTest ( const DtSymbol * s ) [protected, virtual]

virtual void DtObjectSelector::removeSingleSelectionItems	(	DtModelDataIter *	iter,
		QVector< DtModelKey > &
	)		`[protected, virtual]`

Given a list, removes any item that is a "single selection" item.

Currently this is just lines with a point selected

virtual bool DtObjectSelector::isSingleSelectionItem	(	DtModelData *	data,
		DtSymbol *	s
	)		const `[protected, virtual]`
