/**
|
|
*
|
|
* A text field with a pair of up/down spinner buttons and up/down arrow key event listeners attached for
|
|
* incrementing/decrementing the value by the {@link #step} value. Provides automatic numeric validation to limit
|
|
* the value to a range of valid numbers. The range of acceptable number values can be controlled by setting
|
|
* the {@link #minValue} and {@link #maxValue} configs.
|
|
*
|
|
* Example usage:
|
|
* new Common.UI.MetricSpinner({
|
|
* el: $('#id'),
|
|
* minValue : 0,
|
|
* maxValue : 100,
|
|
* step : 1,
|
|
* defaultUnit : 'px',
|
|
* allowAuto : false,
|
|
* autoText : 'Auto'
|
|
* });
|
|
*
|
|
*
|
|
* @property {String} defaultUnit
|
|
* Name of the unit of measurement. Can be px|em|%|en|ex|pt|in|cm|mm|pc|s|ms.
|
|
*
|
|
* defaultUnit: 'px',
|
|
*
|
|
* @property {Boolean} allowAuto
|
|
* True to enable additional field value {@link #autoText}. {@link #autoText} appears when number value of the field
|
|
* is {@link #minValue} and the user pressed down spinner button or down arrow key.
|
|
*
|
|
* allowAuto: false,
|
|
*
|
|
* @property {String} autoText
|
|
* Used when {@link #allowAuto} is true.
|
|
*
|
|
* autoText: 'Auto',
|
|
*
|
|
* @property {Boolean} disabled
|
|
* True if this spinner is disabled.
|
|
*
|
|
* disabled: false,
|
|
*
|
|
* @property {Boolean} hold
|
|
* If true this spinner fires a mouse down/arrow key down event while the mouse/key is pressed.
|
|
* The interval between firings depends on {@link #speed} .
|
|
*
|
|
* hold: true,
|
|
*
|
|
* @property {String} speed
|
|
* Used when {@link #hold} is true. Can be 'slow', 'medium', 'fast'.
|
|
*
|
|
* speed: 'medium',
