Using my custom controls in Design Time

[msd 5]

Hello,

 

I would like to add some extra features to standard Delphi VCL components.

For example, I want to expand the TEdit class with some properties and evets.

When I create class TmyEdit = class(TEdit) in runtime, it works fine. I call the create method and I can use it.

But! I need to have a TmyEdit as a VCL component which can be put in a form at design time and configure some properties and connect some events at design time.

I tried with Initialization RegisterClass(TmyEdit), but the same error is there.

 

The error is: class TMyEdit is not found. Ignoring this error will delete this component...

 

Thanks for any info and advice in advance...

An option I know of is to create your own component based/derived from e.g. Edit. Then follows the creation and installation of the package.
