FileInput.hpp

Specs for the FileInput widget (click on to upload a file)

Todo:

Setup FileInput to work outside of web mode as well.

class FileInput : public internal::WidgetFacet<FileInput>

#include <FileInput.hpp>

FileInput will convert the file to a std::string and pass the result to a designated function.

To create a new file input, you must pass it a void function that takes a const std::string & as its only argument. When a file is loaded, the specified function is called and the body of the file is passed in as the string.
