/**

* SECTION:gtkspinbutton
|
||
* @Title: GtkSpinButton
|
||
* @Short_description: Retrieve an integer or floating-point number from
|
||
* the user
|
||
* @See_also: #GtkEntry
|
||
*
|
||
* A #GtkSpinButton is an ideal way to allow the user to set the value of
|
||
* some attribute. Rather than having to directly type a number into a
|
||
* #GtkEntry, GtkSpinButton allows the user to click on one of two arrows
|
||
* to increment or decrement the displayed value. A value can still be
|
||
* typed in, with the bonus that it can be checked to ensure it is in a
|
||
* given range.
|
||
*
|
||
* The main properties of a GtkSpinButton are through an adjustment.
|
||
* See the #GtkAdjustment section for more details about an adjustment's
|
||
* properties.

|
||
*
|
||
* GtkSpinButtons main CSS node has the name spinbutton. It creates subnodes
|
||
* for the entry and the two buttons, with these names. The button nodes have
|
||
* the style classes .up and .down. The GtkEntry subnodes (if present) are put
|
||
* below the entry node. The orientation of the spin button is reflected in
|
||
* the .vertical or .horizontal style class on the main node.
