Hi Tim

Would it be possible to get a GroupIndex or similar property for TImage?
I've got my own descendant TImage which works fine if dynamically
created, but not when I change the declaration of a TImage placed on a form.

Cheers, Bob

Bob,

This is the one main issue with control descendants - they're simply not
supported in the design-time form designer/form files.

As for the property, yes, I can see about adding a Tag property.

Hi Tim

Even although it's not supported in the designer, I'm having success
with form inheritance where the descendent forms don't involve any new
components added at design time. E.g. I've got a base master-detail form
with grid, layout code, panels etc. I then just change the class
declaration in new forms and add the code that wires up the dataset.
Detail controls are also added at runtime.

I thought I might get away with this approach using individual controls
but when I changed TImage to TrdImage it wouldn't play ball at runtime -
the new property wasn't recognised.

Cheers, Bob

Cool, very ingenious.

I've got an architecture in my head for 3rd party controls at design-time,
so hopefully it won't be much longer after the initial release when I can
put it all into place.

I was actually more impressed with your software than the idea
