Fix potential for dangling pointers in Element.createCommand. #17

Closed nomad-software closed 10 years ago

nomad-software commented 10 years ago

Because the garbage collector cleans up during runtime it may free uniqueData and callback inside the CommandArgs struct when creating a new command. Check and alter the behaviour of the Element.createCommand method to not allow this.

Switched to allocating memory from the GC heap instead of the unmanaged heap when creating a command. https://github.com/nomad-software/tkd/commit/d77ff8603e26e7645c60b2613b996f1b21e751fc
