At runtime, you can check to see if the user has
assigned an event handler to the button and then internally store their handler
and call after your code.

Donovan,
Would
it not be better to expose an OnClick event on your component itself instead of
exposing your internal button? You could call it OnButtonClick to
differentiate it from any other internal control event. This way, you can
perform any code you want before/after you internally
P,
And what happens when the user has no event assigned when the app starts
and then during program operation sets an event handler in
code?

You could handle that by having a Set procedure for
your event field that holds on the users handler.

Actually you can. You can create a customised version of the GINA dll.
Implementing this new DLL naturally depends on how much control you have
over users. If it is the general public I don't see it happening, although
PC Anywhere software does. Also replacing it when another application
Don't publish the actual embedded TButton's OnClick event. Publish your
own (EmbeddedBtnClick) and then in the setter of the property tie the event
to the embedded comoponent.
something like this (extremely rough example)...

Thanks. However unless I am still missing something here then this is
still a problem:
EmbeddedComponent.OnEvent := nil;
TControlLink.Active := TRUE;
EmbeddedComponent..OnEvent :=

Dont see how MyEventAssignedAtRunTimeBecauseICan would ever be
called.

If you have simple requirements then consider having a look at
TClientSocket, TServerSocket on Internet tab. They can be used in Non
Blocking or Blocking (Requires thread) modes. They are heaps easier to
use than Indy and work well.

My example was simple to illustrate the concept. I agree with what you

I Don't really understand, You are truing to hook a TNotifyEvent
The methods were example of how to use RTTI to hook them...

Reading back, I realised I missed a step. You would
have to be working withyour own inherited versionof TButton. Do you
have that much control over it or is this someone elses control?

No I don't have control over that button (class). If was able to subclass

OK, in some sort of design mode? or are they a delphi programmer?
User assigns TButton to MyComponent
So you get a reference to the Button and persist the ref to TButton

Yup,

Solution 5: Make the hooking possible at runtime only. (Don't publish the
button property for your component, just have it as public).

Solution 1: Also hook the double click event so that you can check your
hook
after the double click
Solution 2:
howdy there...
you could get the coordinates on the OnCellClick event sth. like
x := Mouse.CursorPos.X;y := Mouse.CursorPos.Y;
as for detecting which column.. uhh the OnCellClick event has a Column parameter.. guess that works
