Constructor & Destructor Documentation

casa::PlotTool::PlotTool ( PlotCoordinate::System sys = PlotCoordinate::WORLD )

Constructor which takes which coordinate system events should be processed in.

casa::PlotTool::PlotTool	(	PlotAxis	xAxis,
		PlotAxis	yAxis,
		PlotCoordinate::System	sys = `PlotCoordinate::WORLD`
	)

Constructor which takes the two axes and the coordinate system which events should be processed in.

virtual casa::PlotTool::~PlotTool ( )

virtual

Destructor.

Member Function Documentation

virtual void casa::PlotTool::attach ( PlotCanvas * canvas )

protectedvirtual

Attaches this tool to the given canvas.

Detaches from current canvas if necessary.

Reimplemented in casa::PlotSelectTool, and casa::PlotMSAnnotator.

virtual PlotCanvas* casa::PlotTool::canvas ( ) const

protectedvirtual

Returns the canvas this tool is attached to, or NULL for none.

virtual void casa::PlotTool::detach ( )

protectedvirtual

Detaches this tool from its canvas.

Reimplemented in casa::PlotSelectTool, and casa::PlotMSAnnotator.

virtual PlotFactory* casa::PlotTool::factory ( ) const

protectedvirtual

Returns a factory that can be used for generating implementation-specific classes, or NULL for none.

virtual PlotCoordinate::System casa::PlotTool::getCoordinateSystem ( ) const

virtual

Gets the coordinate system in which the tool wants to process events.

Events passed to this tool should use this coordinate system.

virtual PlotAxis casa::PlotTool::getXAxis ( ) const

virtual

Gets the axes on which the tool operates.

virtual PlotAxis casa::PlotTool::getYAxis ( ) const

virtual

virtual bool casa::PlotTool::isActive ( ) const

virtual

Returns whether this tool is currently active or not.

virtual bool casa::PlotTool::isAttached ( ) const

protectedvirtual

Returns true if this tool is attached to a canvas, false otherwise.

virtual bool casa::PlotTool::isBlocking ( ) const

virtual

Returns whether this tool is blocking or not.

When a PlotCanvas encounters a blocking tool, it is expected to not send events to any other handlers further in the chain.

virtual bool casa::PlotTool::lastEventWasHandled ( ) const

virtual

Returns whether the last event was handled or not.

Mostly used for blocking tools so that unused events can be passed along.

virtual void casa::PlotTool::reset ( )

inlinevirtual

Resets any internal state such as history/stacks.

Should be called by the PlotCanvas when the state of the canvases changes (axes ranges, adding/deleting items, etc.) and would thus invalidate tool states.

Definition at line 112 of file PlotTool.h.

virtual void casa::PlotTool::setActive ( bool isActive = true )

virtual

Sets whether this tool is currently active or not.

Reimplemented in casa::PlotSelectTool, and casa::PlotMSAnnotator.

virtual void casa::PlotTool::setBlocking ( bool blocking = true )

virtual

Sets whether this tool is blocking or not.
