IDLgrLegend
Superclasses | Creation | Properties | Methods | Version History
The IDLgrLegend object provides a simple interface for displaying a legend. The legend itself consists of a (filled and/or framed) box around one or more legend items (arranged in a single column) and an optional title string. Each legend item consists of a glyph patch positioned to the left of a text string. The glyph patch is drawn in a square which is a fraction of the legend label font height. The glyph itself can be in one of two types (see the TYPE keyword). In line type, the glyph is a line segment with line style, thickness and color attributes and an optional symbol object drawn over it. In fill type, the glyph is a square patch drawn with color and optional pattern object attributes.
An IDLgrLegend object is a composite object; it is one of the basic drawable elements of the IDL Object Graphics system, and it is not a container for other objects.
This object class is implemented in the IDL language. Its source code can be found in the file idlgrlegend__define.pro in the lib subdirectory of the IDL distribution.
