Detailed Description

draw symbols with text

vtkLegendBoxActor is used to associate a symbol with a text string. The user specifies a vtkPolyData to use as the symbol, and a string associated with the symbol. The actor can then be placed in the scene in the same way that any other vtkActor2D can be used.

To use this class, you must define the position of the legend box by using the superclasses' vtkActor2D::Position coordinate and Position2 coordinate. Then define the set of symbols and text strings that make up the menu box. The font attributes of the entries can be set through the vtkTextProperty associated to this actor. The class will scale the symbols and text to fit in the legend box defined by (Position,Position2). Optional features like turning on a border line and setting the spacing between the border and the symbols/text can also be set.

virtual const char* vtkLegendBoxActor::GetClassName ( ) [virtual]

Reimplemented from vtkActor2D.

static int vtkLegendBoxActor::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkActor2D.

virtual int vtkLegendBoxActor::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkActor2D.

void vtkLegendBoxActor::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkActor2D.

static vtkLegendBoxActor* vtkLegendBoxActor::New ( ) [static]

Instantiate object with a rectangle in normaled view coordinates of (0.2,0.85, 0.8, 0.95).

The vtkPolyData is assumed to be defined in the x-y plane, and the text is assumed to be a single line in height. Note that when this method is invoked previous entries are deleted. Also supply a text string and optionally a color. (If a color is not specified, then the entry color is the same as this actor's color.) (Note: use the set methods when you use SetNumberOfEntries().)
