Hi,

I would like to write a component which should give the possibility of
filtering a DBGrid.

Here are the involved classe (I have removed methods and properties for more
clarity):

TFilterGrid = class (TWinControl)
private
ColFilter: array of TColFilter;
FGridToFilter: TDBGrid;
FMaxColFiltered: Integer;
pnFilters: TPanel;
pnMain: TPanel;
public
constructor Create(aOwner: TWinControl); override;
published
end;

Having already done it for simple thing, I know how to register a component
and make it available on the palette.

But in this case, I am expecting, when I put this component on a Form, that
the whole will appear structured:
- pnFilters has pnMain as Parent and is Top aligned
- FGridToFilter has pnMain as Parent and is Client aligned

Where should I put the code for the alignement?
Is TWinControl the right ascendant?

Do you know where I can find such an example?

I am using Delphi6 Update 2.

Thanks,

Hubert.

In between, I have found out that the keywords for that must be Compound and
Sub-components.

Will try on my own and come again later with probably better questions....
