Constants

The following constants are defined by WebPlugInViewFactory. They define the keys used to access the values in the arguments dictionary passed in to the plugInViewWithArguments: method. Note that WebPlugInBaseURLKey and WebPlugInAttributesKey will always correspond to data, the others may be nil.

Constant

Description

WebPlugInBaseURLKey

The base URL of the document containing the plug-in's view. Required key.

WebPlugInAttributesKey

The NSDictionary object containing all names and values of all attributes of the plug-in’s associated HTML element, as well as all names and values of the parameters to be passed to the plug-in. For example, this dictionary will contain all PARAM elements within an APPLET element. If attribute and parameter names conflict, the attributes of an element take precedence over any of its parameters. All keys and values in this dictionary must be of type NSString. Required key.

WebPlugInContainerKey

An object that conforms to the WebPlugInContainer informal protocol. This object is used for callbacks from the plug-in to the enclosing application. If WebPlugInContainerKey is nil, no callbacks will occur.

WebPlugInContainingElementKey

If an element of the page’s Document Object Model was used to specify the plug-in, this will contain that element. Otherwise, it will be nil.
