This class provides a low-overhead text input field.
This is a virtual base class below Fl_Input. It has all the same interfaces, but lacks the handle() and draw() method. You may want to subclass it if you are one of those people who likes to change how the editing keys work. It may also be useful for adding scrollbars to the input field.
This can act like any of the subclasses of Fl_Input, by setting type() to one of the following values:
#define FL_NORMAL_INPUT 0
#define FL_FLOAT_INPUT 1
#define FL_INT_INPUT 2
#define FL_MULTILINE_INPUT 4
#define FL_SECRET_INPUT 5
#define FL_INPUT_TYPE 7
#define FL_INPUT_READONLY 8
#define FL_NORMAL_OUTPUT (FL_NORMAL_INPUT | FL_INPUT_READONLY)
#define FL_MULTILINE_OUTPUT (FL_MULTILINE_INPUT | FL_INPUT_READONLY)
#define FL_INPUT_WRAP 16
#define FL_MULTILINE_INPUT_WRAP (FL_MULTILINE_INPUT | FL_INPUT_WRAP)
#define FL_MULTILINE_OUTPUT_WRAP (FL_MULTILINE_INPUT | FL_INPUT_READONLY | FL_INPUT_WRAP)
All variables that represent an index into a text buffer are byte-oriented, not character oriented, counting from 0 (at or before the first character) to size() (at the end of the buffer, after the last byte). Since UTF-8 characters can be up to six bytes long, simply incrementing such an index will not reliably advance to the next character in the text buffer.
Indices and pointers into the text buffer should always point at a 7 bit ASCII character or the beginning of a UTF-8 character sequence. Behavior for false UTF-8 sequences and pointers into the middle of a sequence are undefined.
