Detailed Description

This lens Area is the controller of the SymbolLens.

It can draw symbols as well as a background pixmap - and controls the required filters.

Constructor & Destructor Documentation

DtSymbolLensArea::DtSymbolLensArea	(	QWidget *	parent = `0`,
		Qt::WindowFlags	= `0`,
		bool	useGL = `false`
	)

Constructor.

virtual DtSymbolLensArea::~DtSymbolLensArea ( ) [virtual]

Destructor.

Member Function Documentation

virtual void DtSymbolLensArea::setSymbolList ( DtSymbolList * mySymbolList ) [virtual]

virtual DtSymbolList* DtSymbolLensArea::symbolList ( ) [virtual]

return the symbol list or NULL if it doesn't exist.

static DtSymbolLensArea* DtSymbolLensArea::create	(	QWidget *	parent,
		const Qt::WindowFlags &	flags,
		bool	useGL = `false`
	)		`[static]`

Returns a newly created instance of a DtSymbolLensArea.

virtual void DtSymbolLensArea::drawOrderSymbols	(	DtSymbolList *	list,
		bool	addAll
	)		`[virtual]`

This routine will take the current symbol list and order them according to which symbols want to be drawn first or last.

Symbols that aren't draw first or last will be placed after the symbols that are drawn first but before the symbols that are drawn last. If addAll is true, all symbols will be added.

virtual void DtSymbolLensArea::insertIntoDrawOrder ( DtSymbol * ) [virtual]

Insert this symbol into draw order (if exists).

If there is no draw order and this symbol wants a draw order, then draw order symbols

virtual void DtSymbolLensArea::drawOrderSymbols ( ) [virtual]

This routine will draw order the symbols into the myDrawOrder list.

virtual DtSymbolList* DtSymbolLensArea::drawOrder ( ) [virtual]

Returns the draw order list.

virtual void DtSymbolLensArea::clearDrawOrder ( ) [virtual]

Clears the draw order by deleting the draw order list.

virtual void DtSymbolLensArea::setForceDrawOrderAdd ( bool ) [virtual]

If true, add symbols to draw order regardless of whether or not they are on-screen.

virtual bool DtSymbolLensArea::forceDrawOrderAdd ( ) const [virtual]
