GC cleans up for you. Usually this won't happen because uniqueData is likely to be in data section and callback is likely to be a member of a widget used elsewhere. But if they aren't, GC will free them and you end up with dangling pointers in CommandArgs.

I see. I think i have been bitten by this actually. What would be your solution?

Without having looked at the code, call GC.addRoot. It will make sure the GC knows about the memory even if there's no other reference to it.

There is a good readme file and full HTML documentation along with examples there.

Thanks Gary.

Very simple :)

But i have a question.

All DLL file => How can i embed main.d file?

for example:

dmd output => just, main.exe so standalone

sorry for my bad english :/

BTW, there's some info about dragondrop in tk: http://wiki.tcl.tk/571

Hi Kagamin.

You can't, on Windows the DLL's and library folder have to be distributed with your exe. Tkd currently uses these resources:

https://github.com/nomad-software/tcltk/tree/v8.6.2/dist/

Later versions of Tkd will use other DLL's i've compiled to avoid any license issues.

More information is in the readme file.

Hmm... visual designers can usually build pixel-oriented GUI, tk uses layouts, which work with code a little better.
