delphi - I need help on how to implement class that can be shown in object Inspector -

i have

...   tdisppitch = class   private     ilinesize: integer;     ilinecolor: tcolor;     bdisplayaccent: boolean;     bvisible: boolean;   published     property linesize : integer read ilinesize write ilinesize;     ...etc   end; ... 

and wanted feature shown in object insepector edit settings.

i try adding

property disppitch: tdisppitch read fdisppitch write fdisppitch.  

the disppitch can shown cannot see properties. linesize, linecolor etc.

you must derive class tpersistent, or descendant, in order make available in object inspector:

tdisppitch = class(tpersistent) private   ... published   property ...   ... end; 

from delphi documentation:

tpersistent ancestor objects have assignment , streaming capabilities.
