Variable update handler​

This example demonstrates how the

onVariableUpdate
callback persists changes made to an existing variable within the host application. Once the updated variable has been successfully saved, the result is returned to the widget through the

onResponse
callback.
TypeScript
Variable update handler
onVariableUpdate: (variable: DIQ_Variable, onResponse: (result: DIQ_Result) => void) => {

    // Update the variable in the application's database
    database.updateVariable(variable);

    // Notify the widget that the operation completed successfully
    onResponse({
        success: true
    });

};
