Dashboard Info.plist Keys

Dashboard widgets provide information to the system and to Dashboard through the use of an information property list (Info.plist) file. The keys in a widget’s information property list file identify the type of the bundle and the location of the widget’s main HTML file

Table 3-1 lists the custom keys associated with all widgets. Dashboard uses these keys to configure the widget and prepare it for display. To learn more about using these keys in a widget, including a sample Info.plist file that you can base your own widget's Info.plist file off of, read Widget Basics in Dashboard Tutorial.
