Hi!

When programming a GUI, how can I implement drag&drop ("move"
listbox1-items to listbox2).

and drag (upload) external files to an area?

thank you

Most users would employ a framework or library, whether programming a desktop GUI or a browser-based GUI. If you choose not to use a framework or library, then for a browser-based GUI you would have to respond to DOM events, and in a Desktop-based GUI, you would have to issue the appropriate GUI calls to the operating system (in general this is usually done by writing C-code that is callable from Ruby — Ruby doesn’t really give you the tools to make system calls directly, and even if they did coding it in Ruby would result in slow-running code, as Ruby is farther removed from the machine level than C is.

Ok, so how can I do it - using libui, glimmer?
Any gems doing that already (have not found a solution!)
