Constructor Detail

DefaultDisplayRendererJ2D

public DefaultDisplayRendererJ2D()

This is the default DisplayRenderer used by the DisplayImplJ2D constructor. It draws a 2-D box around the scene and a 2-D cursor.

The left mouse button controls the projection as follows:

• mouse drag or mouse drag with Ctrl translates the scene sideways
• mouse drag with Shift down zooms the scene

The center mouse button activates and controls the 2-D cursor as follows:

• mouse drag translates the cursor sideways

The right mouse button is used for direct manipulation by clicking on the depiction of a Data object and dragging or re-drawing it.

Cursor and direct manipulation locations are displayed in RealType values

BadMappingExceptions and UnimplementedExceptions are displayed

No RealType may be mapped to ZAxis, Latitude or Alpha.

DefaultDisplayRendererJ2D

public DefaultDisplayRendererJ2D(Class mbj2dClass)

Parameters:

mbClass - - sub Class of MouseBehaviorJ2D

Method Detail

getMode2D

public boolean getMode2D()

Description copied from class: DisplayRenderer

Return true if this is a 2-D DisplayRenderer.

Overrides:

getMode2D in class DisplayRenderer

Returns:

true if this is a 2-D renderer.

legalDisplayScalar
