Not obscure at all ;-) but a very difficult point.
I have think a little about this and i have notice 2 things.
* With only one event fonction (actual NEM)
it's possible to call the DoSomethingElse function in the DoSomething
function.
And in case of 'overriden' a sub package event, just need to call the event
function.
sub overriden_OnClick {
my $self = shift;
# do something before
$self->OnClick(); # or in inherited package $self->SUPER::OnCLick();
# do something after
}
The package use the \& syntax and not sub { } in the event option.
But for instanced object, it's possible to use sub {}.
* With event queue
Problem for the new package method.
For example :
- the package need to add a click event function
- the user create an object with a click event function
How create the click event array ?
- order problem between user event and package event.
- If user don't want default package click event.

After some search about this point, I found a free open source code project
named FreeImage.
It's a library for loading and writing different file format (JPEG, PNG,BMP,
PCX, TIFF, TGA).
I have look some example, it's look easy to use.
It's possible to read the data image not only from file (just need to code
an io-handler).
It can be usefull for read image from perl variable (no tempory file in the
BitmapInline.pm or
interface with perl GD module).

I can help you for this point.

This text control look very nice.
