### Description

The `Fl_Value_Input` widget displays a numeric 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)` or `type(FL_INT_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 non-zero and integral, then the range of numbers is limited to integers instead of floating point numbers. As well as displaying the value as an integer, typed input is also limited to integer values, even if the hidden `Fl_Input` widget is of `type(FL_FLOAT_INPUT)`.

If `step()` is non-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 right button by `100 * step()`. It is therefore impossible to select text by dragging across it, although clicking can still move the insertion cursor.

If `step()` is non-zero and integral, then the range of numbers are limited to integers instead of floating point values.

- cursor_color
- soft
- textcolor

- textsize

#### Fl_Value_Input::Fl_Value_Input(int x, int y, int w, int h, const char *label = 0)

Creates a new `Fl_Value_Input` widget using the given position, size, and label string. The default boxtype is `FL_DOWN_BOX`.

#### virtual Fl_Value_Input::~Fl_Value_Input()

Destroys the valuator.

#### Fl_Color Fl_Value_Input::cursor_color() const
void Fl_Value_Input::cursor_color(Fl_Color)

Get or set the color of the text cursor. The text cursor is black by default.

#### uchar Fl_Value_Input::soft() const
void Fl_Value_Input::soft(uchar)

If "soft" is turned on, the user is allowed to drag the value outside the range. If they drag the value to one of the ends, let go, then grab again and continue to drag, they can get to any value. The default is true.

#### Fl_Color Fl_Value_Input::textcolor() const
void Fl_Value_Input::textcolor(Fl_Color)

Gets or sets the color of the text in the value box.

#### Fl_Font Fl_Value_Input::textfont() const
void Fl_Value_Input::textfont(Fl_Font)

Gets or sets the typeface of the text in the value box.

#### uchar Fl_Value_Input::textsize() const
void Fl_Value_Input::textsize(uchar)

Gets or sets the size of the text in the value box.
