SMS:Dynamic Model Interface Schema

The dynamic model interface is available in SMS version 11.2 and later. It is primarily a tool for developers. The dynamic model interface provides a way to quickly generate an interface for a numeric model.

Dynamic dialogs are a quick way to generate dialogs without having to compile code. To add or delete a widget on a dynamic dialog, the user simply modifies the XML document. When the modified document is loaded, the new/modified dialog exists. The XML document defines the layout, behavior and the different dialog controls.

The dialog is divided into 2 sections, the tree and the widget view. The tree is on the left side of the dialog and it contains groups and items that represent data. Clicking on a group or item will result with the widget view being updated to match the selected tree or group item.

• Order of the tree items and groups will match the order defined in the XML file.
• Clicking on group will display all children items in the widget view.
• Clicking on a single item will display associated widgets in widget view.
• Tree item will also display the values in a non-editable field.
• Unique_name use format: file::unique_name#value
• Widgets or groups of widgets can be loaded from an outside file by using <link_to_xml>.
• Multiple widgets when displayed on right side can be expanded/collapsed – TO BE DETERMINED
• Can have nested groups
• Keywords are words SMS has reserved in the schema and can not be used as unique names. All keywords will start with a “#”. Here is a list of available keywords:

• #card_name
• #geom_name – name of geometry as it shows up in the project explorer
• #project_name
• #value
• #units
• #xmdf_path – path inside the XMDF file
• #file_name
• #file_path
• #sms_path – path in sms project explorer once inside a geometric item
• #count (used for a widget in a table for counting the rows/columns)
• #geom_guid

Projection keyword:

• #horizontal_datum: NAD83 |NAD27|LOCAL
• #horizontal_system: UTM|STATE_PLANE|GEOGRAPHIC|LOCAL
• #horizontal_units: FEET|METERS|DEGREES
• #horizontal_zone: 3104 etc
• #vertical_datum
• #vertical_units

Additional keywords are defined with the various custom control widgets.

Note: In changing from version 1 to version 2, all tags that were <custom_control_XXXX> were changed to <control_XXXX>.
