Linking objects to a data source
Prefixes (Scene:, Control:, Data:, L:, G:)
Xstudio uses prefixes to specify the origins of objects and data. For example, when
assigning data to an object you must indicate whether the object is part of the scene or the
control side.
While you can type these in along with the object name or data source, Xstudio’s drag and
drop functionality makes it unnecessary for the most part by automatically filling all required
information.
Local and global database variables are created on the fly whenever a reference to one is
made in a property value or action parameter. You are not required to create these variables
in the Data Manager. It is also possible for controls to set the value of these variables such
that other controls may read them. Local database variables can only be used within the
control panel that created them and are destroyed when the panel exits Production mode.
Global database variables, on the other hand, are shared amongst all control panels and
remain in the database even after exiting Production mode.
Prefix Signifies
Scene: A scene object, e.g. Scene:Clip1Control:DropboxMonth.
Control: A control object, e.g. Control:MyControlObject.
Data: A data item from the Data Server, e.g. Data:Schools:SchoolsClosed(1,1).
L: A local data server variable, e.g. L:SelectedStock.
G: A global data server variable, e.g. G:StationID.
