# Gtk::CellRendererSpin Class Reference
[TreeView Classes]

Inheritance diagram for Gtk::CellRendererSpin:

List of all members.

## 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.

Since gtkmm 2.12:

## Member Function Documentation

virtual Glib::PropertyProxy_Base Gtk::CellRendererSpin::_property_renderable | ( |  | ) | `[virtual]`

Returns the property that this CellRenderer renders.

For instance, property_text for CellRendererText, and property_active for CellRendererToggle Needs to be overridden in derived classes.

Reimplemented from Gtk::CellRendererText.

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

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.

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.
