Properties

Properties are specific to the widget that is using the appearance key where the properties are defined. Some properties are translated to "style" settings on the widget DOM element, while others may only affect internal behavior.

Each widget decides how to use a property. Unlike styles, properties are not limited by CSS specs.

Common Properties

This is the list of the common (shared) properties by all widgets. However, specific widgets may have additional themeable properties that are not listed here. See the Other Properties section for more information on how to find out which properties to use in a theme.

Other Properties

All the properties that are marked themeable in the widget's JavaScript code can be defined in a theme.

One way to find which properties are supported is to use the excellent qooxdoo API viewer and search for a base widget that corresponds to the Wisej.NET control. When using the API Viewer, note that themeable properties show a pencil icon.

Another way is to look at the JavaScript source code for the Wisej.NET widgets and their base classes to determine which properties are themeable.

/**
 * CheckAlign property.
 *
 * Gets or sets the horizontal and vertical alignment of the check mark.
 */
checkAlign: {
	themeable: true,
	init: "middleLeft",
	apply: "_applyCheckAlign",
	check: ["topRight", "middleRight", "bottomRight", "topLeft", "topCenter", "middleLeft", "middleCenter", "bottomLeft", "bottomCenter"]
}

Property Group

Property groups are composite properties that can set the values of other properties using a shorthand array. The code below shows a property group used to set related properties. In a theme definition file you can set a property group or a single property or both; they are applied in the order they are declared.

"properties":
{
  "padding": [4, 0, 2, 4]
}

The definition above is equivalent to:

"styles":
{
  "paddingTop": 4,
  "paddingRight": 0,
  "paddingBottom": 2,
  "paddingLeft": 4
}
