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

Coverage keywords:

• #area_property
• #activity_classification
• #cgrid_generator
• #location
• #mapping
• #mesh_generator
• #observation
• #quadtree_generator
• #spectral

executable_progress_update keywords:

• #progress_amount
• #progress_max

Material keywords:

• #material_id
• #material_name
• #material_count
• #unassigned

Point keywords:

• #point_count
• #point_id
• #point_x
• #point_y
• #point_z

Arc keywords:

• #arc_id
• #arc_count
• #arc_point_count

Polygon keywords:

• #polygon_id
• #polygon_count
• #polygon_point_count

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>.

Element <control_dataset>

Info	Displays an edit box, and push buttons for select, delete and create. Once selected, the dataset string is placed into the edit box. The dataset_type can be scalar or vector. Possible keyword outputs are file_name (which is the name of the dataset without path), geom_name, and file_path (full path c:\somewhere) and sms_path. By default, all datasets of geometries that are part of the simulation (or part of the parameters if one or more use_parameter is used) can be selected. The the geometry attribute is set to “all”, then the datasets from all geometries currently loaded into SMS can be selected from, regardless of relation to the simulation and assuming no other attribute prevents it. If “all” is used, then the dataset values will be interpolated to the geometry in the simulation. The time_type attribute can be set to “all” (default), “transient”, or “steady state”. When “transient” is used, only datasets with multiple timesteps may be selected. When “steady state” is used, only timesteps without timesteps may be selected. The select_time attribute can be set to “all” (default), “single”, or “range”. If “single” is used, then only a single timestep of the dataset will be selected. If “range” is used, then both a starting and ending timestep can be selected. By default, all timesteps of a dataset are used. (For possible future use.)The interpret_time attribute can be set to “true” or “false” (default). When true, this attribute tells SMS to interpolate dataset values at the timesteps in the selected dataset to values at timesteps calculated from a start time, end time, and delta time that is specified by the user.

The model may be one that is already defined by another XML file. Dialogs can be specified for data that will be kept for the model, but will not be shown to the user.
