Constructor & Destructor Documentation

casa::PanelDisplay::PanelDisplay	(	PixelCanvas *	pixelcanvas,
		const Int	nx = `3`,

		const PanelDisplay::FillOrder	order = `LEFT_TOP`
	)

Constructor taking: a pointer to the PixelCanvas on which to lay the panels, the number of panels in the x and y directions, the extent of the PixelCanvas to cover with panels, and the fractional spacing between the panels.

virtual casa::PanelDisplay::~PanelDisplay ( ) [virtual]

Destructor.

Member Function Documentation

int casa::PanelDisplay::getColumnCount ( ) const

Returns the number of columns of plots that are currently being displayed.

float casa::PanelDisplay::getDrawUnit ( ) const

Returns the current mapping of PGP units to pixel units.

This number varies depending on the data units of the plot.

	)		const `[virtual]`

Describe or set the geometry of the panels, either explicitly or in RecordInterface form.

(Note: setGeometry() does not automatically refresh; when called within setOptions it does, though.)

List<WorldCanvasHolder* > casa::PanelDisplay::itsWCHList [private]

ListIter<WorldCanvas* >* itsWCLI;.

The WorldCanvasHolders which we made, and a convenient iterator.

(dk note: you should create a local iterator instead of using member iterators. Otherwise, a call chain may include two methods in the class stepping on each other's iterator use. Even if you think that won't happen currently, it creates a maintenance minefield).

Also note: exactly the same list (with the same name, even) is maintained on MWCH level (to be fixed).

Reimplemented from casa::MultiWCHolder.
