|
* @short_description: style information for one node in a tree of
|
|
* themed objects
|
|
*
|
|
* A #EekThemeNode represents the CSS style information (the set of
|
|
* CSS properties) for one node in a tree of themed objects. In
|
|
* typical usage, it represents the style information for a single
|
|
* #EekElement. A #EekThemeNode is immutable: attributes such as the
|
|
* CSS classes for the node are passed in at construction. If the
|
|
* attributes of the node or any parent node change, the node should
|
|
* be discarded and a new node created. #EekThemeNode has generic
|
|
* accessors to look up properties by name and specific accessors for
|
|
* standard CSS properties that add caching and handling of various
|
|
* details of the CSS specification. #EekThemeNode also has
|
|
* convenience functions to help in implementing a #EekElement with
|
|
* borders and padding.
