Abstract:
This unit defines the TObjectInspector.
It uses TOIPropertyGrid and TOIPropertyGridRow which are also defined in this
unit. The object inspector uses property editors (see TPropertyEditor) to
display and control properties, thus the object inspector is merely an
object viewer than an editor. The property editors do the real work.
ToDo:
- backgroundcolor=clNone
- replace pair splitter with splitter
- Define Init values
- Set to init value
}
