A graphic object is said to be zoomable if its bounding box
follows the zoom level. Otherwise, the object is nonzoomable. For
instance, IlvLabel objects are nonzoomable while IlvZoomableLabel objects are zoomable. To
determine whether a graphic object is zoomable, use its boolean
zoomable() method or check its documentation.
If all the graphic objects of an
IlvManager
instance are zoomable, a layout obtained on the basis of the graph
geometry in manager coordinates will appear the same for any value
of the transformer used for the display. Simply speaking, the
drawing of the manager will just be zoomed, or translated.
When at least one nonzoomable graphic object is used as a label or
obstacle, the geometry in manager coordinates can no longer be
used. When drawn with different transformer values (for instance,
at different zoom levels), the same
IlvManager
instance may look very different. In this case, you cannot use
multiple manager views because only one of them can look correct.
All other views will look wrong.
