Constant deletion handler​

This example demonstrates how the

onConstantDelete
callback removes an existing constant from the host application's persistent storage. Once the constant has been successfully deleted, the result is returned to the widget through the

onResponse
callback.
TypeScript
Constant deletion handler
onConstantDelete: (constant: DIQ_Constant, onResponse: (result: DIQ_Result) => void) => {

    // Delete the constant from the application's database
    database.deleteConstant(constant.key);

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

};
