The Tag Widget Reference Folder

When you click the Draw command for a tag in the Tag Browser, VTScada will check the list of Tag Widget Reference Folders for an entry matching the type of tag you are about to draw. If found, you will be given the matching list of widgets to choose from. If there is no matching reference folder, then VTScada will make a longer search for widgets that can be used with a type, and present a list of folders containing those widgets.

When there is a small set of widgets that match a type then it is more efficient for those to be grouped together in a reference folder.

For example, there is a reference folder for the Roster type, containing the widgets most commonly used when drawing that type. When drawing a Roster, you will see only those widgets.

By contrast, the Analog Status tag can be represented by many types of widgets, found in many folder groups. It is also common for developers to create their own widgets that can be linked to the Analog Status. In this case, it is better to let VTScada search out all matching widgets and present those, still grouped by folder.

If you were to create a new widget for Roster types, then you might add a Menu Item for it to the folder referenced by the Rosters entry in this list: [Widgets\Tag Type Widgets\Communications\Alarm Dialer\Roster Widgets]. Note however, that there is no requirement that you do anything at all with these reference folders.

If you have a custom tag type and have created several widgets that may be linked to that type, you can achieve the effect of having a Tag Widget Reference Folder by placing those widgets into a folder that is named after your custom type. This folder may be placed anywhere in the Widgets hierarchy.
