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.

Public Functions

inline FileInput(const std::function<void(const std::string&)> &in_cb, const std::string &in_id = ""): Create a new FileInput; supply the function to call with the file contents as a string (and optionally the HTML identifier to be used).

inline FileInput(const std::function<void(File)> &cb, const std::string &in_id = ""): Create a new FileInput; supply the function to call with the file contents as a File object (and optionally the HTML identifier to be used).

FileInput(const FileInput &in) = default: Load a pre-existing FileInput object.

inline FileInput(const Widget &in)

virtual ~FileInput() = default

inline FileInput &Callback(const std::function<void(const std::string&)> &in_cb): Change the callback function to use when a new file is loaded.

inline FileInput &Autofocus(bool in_af): Set this FileInput object to have autofocus (or not)

inline FileInput &Disabled(bool in_dis): Set this FileInput object to be disabled (or reenable it.)

inline bool HasAutofocus() const: Determine if this object currently has autofocus.

inline bool IsDisabled() const: Determine if this object is currently disabled.
