Description

The Fl_Value_Input widget displays a floating point value. The user can click in the text field and edit it (there is in fact a hidden Fl_Input widget with type(FL_FLOAT_INPUT) in there), and when they hit return or tab the value updates to what they typed and the callback is done.

If step() is not zero, the user can also drag the mouse across the object and thus slide the value. The left button moves one step() per pixel, the middle by 10 * step(), and the left button by 100 * step(). It is then impossible to select text by dragging across it, although clicking can still move the insertion cursor.
