Change the Default Behavior of Components

Many of the behaviors of VertiGIS Studio Web's built-in components are configurable through the app config.

tip

Many behaviors which are configurable through the app config are more easily configurable by using the VertiGIS Studio Web Designer. App config should be used if you need to modify a property not available in the app config, or use a custom command as part of a command chain.

Prerequisites​

Change the Behavior of the Bookmarks Component​

The following example demonstrates changing the onClick property of the bookmarks model. The default value of this property is the singular command, map.zoom-to-viewpoint. This property is not available to edit through the VertiGIS Studio Web Designer, but can be edited through the use of app config.

First, let's create a basic map with a bookmarks component using the layout and app config. Start up the application and add a few bookmarks.

app/layout.xml
<?xml version="1.0" encoding="UTF-8"?>
<layout xmlns="https://geocortex.com/layout/v1" xmlns:custom="your.custom.namespace" xmlns:web="https://geocortex.com/layout/web/v1">
    <map>
        <web:bookmarks/>
    </map>
</layout>

Next, add an app item to the configuration for the bookmarks component.

app/layout.xml
<?xml version="1.0" encoding="UTF-8"?>
<layout xmlns="https://geocortex.com/layout/v1" xmlns:custom="your.custom.namespace" xmlns:web="https://geocortex.com/layout/web/v1">
    <map>
        <web:bookmarks config="bookmarks-config"/>
    </map>
</layout>

Finally, modify the onClick property of the bookmarks app item to run the commands map.zoom-to-viewpoint and ui.alert.

app/app.json
{
    "schemaVersion": "1.0",
    "items": [
        {
            "id": "bookmarks-config",
            "$type": "bookmarks",
            "onClick": [
                "map.zoom-to-viewpoint",
                {
                    "name": "ui.alert",
                    "arguments": {
                        "message": "Message from config."
                    }
                }
            ]
        }
    ]
}

Congratulations! You just changed the default behavior for a built in component using config. All components can be configured through the app config JSON in this manner.

Next Steps​

VertiGIS Studio Web comes with many built-in commands and operations to help you accomplish your goal. If these are not enough, VertiGIS Studio Workflow can help you implement custom behaviors without writing custom code. If you cannot create the behavior you want with VertiGIS Studio Workflow, it might be time to look into using the VertiGIS Studio Web SDK to implement a custom command or operation.
