Variable deletion handler​

This example demonstrates how the

onVariableDelete
callback removes an existing variable from the host application. Once the variable has been successfully deleted, the result is returned to the widget through the

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

    // Remove the variable from the application's database
    database.deleteVariable(variable.key);

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

};
