Detailed Description

Grapher link annotated with a label.

Library: ilvgrapher

Links of the IlvLinkLabel class are labeled with a user-defined character string:

- IlvLinkLabel -

Constructor & Destructor Documentation

IlvLinkLabel::IlvLinkLabel	(	IlvDisplay *	display,
		const char *	label,
		IlBoolean	oriented,
		IlvGraphic *	from,
		IlvGraphic *	to,
		IlvPalette *	palette = 0
	)

Constructor.

Initializes a new instance of the IlvLinkLabel class. The string label is internally copied and appears next to the link.

Parameters

display	The display connection that handles the drawing of this object.
label	The label for the link.
oriented	A Boolean indicating whether an arrowhead is to be drawn at the end of the link.
from	The IlvGraphic object representing the start node of the link.
to	The IlvGraphic object representing the end node of the link.
palette	The palette used to draw the link and its label.

Member Function Documentation

const char* IlvLinkLabel::getLabel

(

)

const

Returns the text label of the link.

Returns

The text label of the link. You must not delete or modify the returned string.

void IlvLinkLabel::setLabel

(

const char *

label

)

Sets the text label of the link.

Creates a copy of the label parameter, which must be a pointer to a valid character string.

Parameters

label

The new label.

virtual IlBoolean IlvLinkLabel::zoomable ( ) const

virtual

Returns the zoomable property of the link.

A link is considered zoomable if both its start and end nodes are zoomable.

Returns

IlTrue if the link is zoomable and IlFalse otherwise.
