====== behavior: number ======
Number input element behavior. If element has //step// attribute defined then it will rendered with spin buttons.

===== Elements =====
that have this behavior applied by default (see [[master style sheet]]): 
  *  ''<input type="number" />'' - inline single line 
  *  ''<widget type="number"></widget>'' 





===== Attributes =====
that this behavior knows about:
  *  ''value=integer'' - initial value of the input element
  *  ''size=integer'' - determines value of (intrinsic and default) width of the element. Default value is 20.
  *  ''minvalue=integer'' - determines minimum value of the element.
  *  ''maxvalue=integer'' - determines maximum value of the element.
  *  ''step=integer'' - if provided shows spin buttons, click on them increments the value correspondingly to this attribute.

If user will input value that is out of minvalue..maxvalue range then the behavior will create attribute //invalid// in the element. Therefore element can be styled separately for invalid state.

<note>
''size'', ''step'', ''minvalue'' and ''maxvalue'' attributes can also be defined in CSS as custom attributes ''-size'', ''-step'', ''-minvalue'' and ''-maxvalue'' correspndingly.
Thus you may define it for group of input elements as:
  input.numeric 
  {
    behavior:number;
    -step:"1"; 
    -minvalue:"0";
    -maxvalue:"100";
  }
</note>

===== Events =====
Together with the standard set of events (mouse, keyboard, focus) //behavior: button// generates:
  *  EDIT_VALUE_CHANGED event - value of the element was changed due to user actions. Posted (asynchronous) event.
  *  EDIT_VALUE_CHANGING event - sent when value of the element is about to change. Synchronous event.

===== Value =====

type json::value::V_INT, reflects current status of internal editing buffer.
===== Special key combinations =====

See [[h-smile:built-in-behaviors:edit]]
===== Methods =====

The behavior supports following ''xcall()'' methods (see dom::element::xcall() function):

  * ''xcall("min"): int'' - returns min limit;
  * ''xcall("min", v:int)'' - sets min limit;
  * ''xcall("max"): int'' - returns max limit;
  * ''xcall("max", v:int)'' - sets max limit;
  * ''xcall("step"): int'' - returns step value;
  * ''xcall("step", v:int|undefined)'' - sets/clears step;

Note that in Sciter you can access these methods simply as:

<code>
  var edit = self.select("input[type='number']");
  edit.min(123);
  var m = edit.min();
</code>

Same notation can be used in CSSS!
