Hi Everyone,

I have developed a CAD component and i'm in the process of developing an
object inspector for it, possibly similar to the Delphi IDE Object
inspector.

My problem is that i am not sure of the best component to derive from... i
have narrowed it down to a few...

- TCustomGrid
- TCustomListBox
- TListView

I know there are third party object inspectors out there but I will need to
distribute the source code and therefore must write it myself.

The main need for the inspector is "inplace" edits, combo's, spin buttons
ect (depending on the property) which must scroll as the component is
scrolled.

Could anyone shed some light on which would be the best component to inherit
from possibly outlining the advantages and/or disadvantages of these
components.

Thanks for your time,

Graham

I believe this is the way Borland have done their OI.

There is one in JVCL, which is under MPL so free to distribute. And no,
you don't have to make your own application OpenSource by using it.

JvInspector can do that.

I think you're best bet would be TCustomListBox, although I can't really
say why <g> It's a gut feeling. If possible in your case you may be better
of using JvInspector.

What's that noise in the background? Oh, it's The Nits with "The train".

Hi,

Why don't you use TValueListEditor which inherit from TCustomGrid.

It is the same behavior than the Delphi's object inspector.

I would suggest subclassing from TCustomGrid. I have done it long ago in the
Delphi 2's era Smile

Looking at the TDBGrid source could give you some hints.
