List variables handler​

This example demonstrates how the

onListVariables
callback retrieves variables belonging to a specific variable folder from the host application. Once the variables have been retrieved, the result and variable list are returned to the widget through the

onResponse
callback.
TypeScript
List variables handler
onListVariables: (folder: DIQ_VariableFolder, onResponse: (result: DIQ_Result, variables: Array<DIQ_Variable> | null) => void) => {

    // Retrieve variables belonging to the selected folder
    const variables = database.getVariablesByFolder(folder.key);

    // Return the variables to the widget
    onResponse({
        success: true
    }, variables);

};
