## Detailed Description

Renders a spin button in a cell.

Gtk::CellRendererSpin renders text in a cell like Gtk::CellRendererText, from which it is derived. But while Gtk::CellRendererText offers a simple entry to edit the text, Gtk::CellRendererSpin offers a Gtk::SpinButton widget. Of course, that means that the text must be parseable as a floating point number.

The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. Gtk::CellRendererSpin also has properties for the climb rate and the number of digits to display. Other Gtk::SpinButton properties can be set in a handler for the start-editing signal.

## Member Function Documentation

GtkCellRendererSpin* Gtk::CellRendererSpin::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::CellRendererText.

const GtkCellRendererSpin* Gtk::CellRendererSpin::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::CellRendererText.

Glib::PropertyProxy_ReadOnly<Gtk::Adjustment*> Gtk::CellRendererSpin::property_adjustment | ( |  | ) | const

The adjustment that holds the value of the spinbutton.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<Gtk::Adjustment*> Gtk::CellRendererSpin::property_adjustment | ( |  | ) |

The adjustment that holds the value of the spinbutton.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<double> Gtk::CellRendererSpin::property_climb_rate | ( |  | ) |

The acceleration rate when you hold down a button.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

## Friends And Related Function Documentation

Gtk::CellRendererSpin* wrap | ( | GtkCellRendererSpin * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
