NetAlive DocumentationA list box controlling the type of widget. Different types of widgets have a different appearance on the user interface (including no appearance), have different behaviors, and interpret the other parameters differently.
The data contained in a widget will be tied to an external file if the file name parameter is non-empty. When tied to an external file, the data is initialized with the contents of the file when the widget is first displayed. Subsequent changes to the data cause the file to be changed on disk to represent the new value.
A widget's data takes different forms depending on its type. Screen controls like text boxes, list boxes, and buttons have textual data. A HTML widget contains textual data interpreted as HTML. A picture widget contains binary data that creates a graphic image. A widget's data is influenced by "Load from caption" and "Field."
If the field parameter is non-empty, the data is taken to be lines consisting of a series of fields. See field tutorial.
The data contained in a widget will be stored in the internal data field of the widget if the file name parameter is empty. When stored internally, the data is initialized with the contents of the internal data field when the widget is first displayed. Subsequent changes to the data cause the internal data to be changed in the document. Changes to internal data are not permanent unless the document is saved to disk.

The insert button starts a procedure where an object replaces the widget's data. The procedure first presents the operating system's Insert Object dialog. After selecting an object type, the application responsible for that object type gives the user a chance to create an object. The object is stored in an external file if the file name parameter is not empty. Otherwise, the object is stored in internal data.
In a Microsoft Window's implementation, object refers to an Object Linking and Embedding (OLE) object.
Note: This button used to be named "Load."
The load/store button changes the widget between storing data in an external file and storing it internally.
Pressing the store button when the widget has internal data stores the data in a file. To store internal data, the user needs to set the file name field and then press the load button. This makes NetAlive write the internal data to the file specified by the file name field and set the internal data to empty.
Pressing the load button when the widget has no internal data loads data from an external file to internal data. To load internal data, the file name field must name the file with the desired data. Pressing the load button causes NetAlive to read the file into internal data and set the file name field to empty.
The edit button invokes application specified for editing the widget's data. When editing completes, the data is updated.
The load from caption option forces the task's caption to be used as its data. Load from caption overrides the file name and internal data fields. Data set by "load from caption" cannot be changed. Note: load from caption applies only to Button widgets at this time.
Affects synchronization of inputs. See synchronization tutorial.
Note: This parameter used to be named "add/delete list box."
This parameter enables the add/delete features of a list box. See listbox documentation.
This parameter enables the history feature of a HTML widget. See HTML widget documentation.
This parameter has no effect on other widgets.
Controls the computer on which the widget executes. See addressing tutorial.
NetAlive switches to view specified by the goto parameter when the widget fires. If the parameter is empty, there is no switching. See view tutorial.
Reserved. Should be unchecked.
